How fast is turbo charged road runner
They would use the same winning formula and bring the same high-level of competition as they stepped it up to the Renegade ranks. The glaringly obvious rule differences allowed for a larger turbocharger and an air-to-water intercooler. Frank also updated the car, slathering the Mustang in blue paint with Bud Lite inspired graphics. The B-Team would eventually strip the car of its GT ground effects two years ago in the name of weight savings, giving it the look it carries into competition today.
Despite his humble memory the team appeared to have their game plan firmly set in place by evident of the results. They walked away with the Renegade record and a class win. Frank went on to win a second championship in with the Renegade car and his teammate collected the Coyote Modified title.
Coming off a race season like that is a challenge for any team with a target on their back, but Frank scored a Top 10 finish in and was runner-up in the championship hunt in How long and how often you can utilize the benefits of either one is very important to consider. Turbochargers are complex and hard to maintain. The average turbocharger needs to be replaced every kk miles; otherwise, it can potentially damage the engine.
Turbochargers have become attractive to automakers in recent years, mainly because they deliver more power to smaller fuel-efficient engines. Ultimately, this makes turbochargers less reliable in the long run.
Sometimes the added complexity means trouble arise down the road. Many car owners expect their vehicle to reach the kk mile mark before putting their car out to pasture.
Superchargers are arguably more reliable than turbochargers. Both offer unique advantages that come with a price. In a nutshell, turbochargers are efficient, inexpensive, and can help many small-engine vehicles obtain engine power advantages. Superchargers are all about dramatic power boosts at any cost. Just how powerful are superchargers? Fully digital instruments visually float on a linear-themed dash. Flowing door-to-door and into a console integrating prominent twin grab handles, the wide trim insert is available in a variety of woods, sleek aluminum, or woven metal.

Post-combustion gases in exhaust port may be at a pressure in FIG. In one embodiment, exhaust valve 16 may be opened with an actuator that may be, e. A second exhaust cam lobe may be formed on the existing exhaust cam or on a separate cam. Although the various embodiments of the invention are described in the context of intake valve and exhaust valve as poppet valves, other types of valves such as, e.
In one embodiment, shown in FIG. Turbo-charger may, e. In this case compressor could supply pressurized pre-combustion gases to clutch-driven compressor while a clutch is engaged, which will in turn compress further the already pressurized pre-combustion gases and supply them to combustion chamber This may be particularly useful when, e.
In this case the amount of energy available might be too low to provide adequate power by turbine to drive compressor through shaft Valve may be dosed while, e. In one embodiment, pre-combustion gases are supplied solely from compressor with clutch disengaged or slipped. This may occur when an engine speed or load is high. Under these conditions, energy in post-combustion gases is adequate to power turbine sufficiently to drive compressor through shaft and produce adequate boost.
Valves and are closed while valve is open. Clutch Is a clutch In the generic sense, meaning any convenient means of providing intermittent or interruptable transmission of power, and may be, e. Clutch may also be a continuously variable transmission, such as a belt on pulleys of variable radii, an electric generator driving an electric motor, or a hydraulic turbine driving an impeller, as shown in FIG.
The pressure prevailing inside a normally-aspirated combustion chamber while intake valve is open will, in general, be at or below substantially ambient pressure for at least part of a cycle. Turbo-charged pre-combustion gases will be, in general, at a pressure higher than ambient pressure. The pressure prevailing Inside exhaust manifold will thus also be higher than that prevailing inside a normally aspirated combustion chamber while intake valve is open, and, consequently, while exhaust valve is also open, for at least part of a cycle.
Since the volume of pre-combustion gases delivered to combustion chamber may be controlled by, e. Since post combustion gases will, in general, move to regions of lower pressure, the volume of post combustion gases returning to combustion chamber when exhaust valve is open may also be controlled by adjusting the pressure in combustion chamber relative to that of exhaust manifold If, e.
Since post-combustion gases would then be at a higher pressure than that of combustion chamber , some post-combustion gases would be returned to combustion chamber when both intake valve and exhaust valve were open.
Since the conditions calling for the addition of post-combustion gases may be generally constant over several cycles of engine operation, the control of clutch would not need to change constantly or instantaneously. Once a particular set operating conditions was reached, the amount of pressure in combustion chamber relative to that of exhaust manifold could be relatively constant.
Post-combustion gases could thus, e. A take-down at, e. An exhaust pulse may thus travel the length of a runner of exhaust manifold , be reflected, or echoed, at the take-down, and return. Such an exhaust pulse would require a certain amount of time to make the round trip. The time required would depend on, inter alia the length of the runner and the pressure differential across the runner. In one embodiment, the length of the runner could be matched to the time an exhaust pulse would be expected to require to complete the round trip.
Thus, for a given engine speed, such as e. Thus, a returning exhaust pulse would reach exhaust valve while it was open to admit post-combustion gases to combustion chamber while intake valve was open, i. In a similar manner, a length of intake manifold runners can be varied to provide lower pressure in combustion chamber relative to that of exhaust port which would increase the amount of post-combustion gases transported to the combustion chamber when both intake valve and exhaust valve are open.
A runner length could be varied by, e. The length of a runner however, is not easily changed after an engine has been built. The timing of the exhaust pulses may thus be tuned for only a narrow range of engine speeds, and harmonics thereof.
In a preferred embodiment, the amount of pressure in combustion chamber relative to that of exhaust manifold , i. The pressure differential could thus be controlled to substantially ensure that an exhaust pulse was returning just as exhaust valve was open during post-bump over a wider range of engine speeds.
The timing of the opening of exhaust valve may be changed to affect the timing of the exhaust pulses as well. This would result in a larger pressure differential across the exhaust manifold runner, adding impetus to the exhaust pulse, speeding it up so it arrived sooner. The tuning could be accomplished, e. If, on the other hand, the exhaust pulses were arriving early, the amount of pressure in combustion chamber relative to that of exhaust manifold could be raised.
This would result in a smaller pressure differential across the exhaust manifold runner, impeding the exhaust pulse and slowing it down so it arrived later. In another embodiment, turbo-charger may include, e. In still another embodiment, turbo-charger may include, e. Shutoff valve may be used to control the pressure in the combustion chamber relative to the pressure in e.
Shutoff valve may be, e. Turbo-charger may be, e. In the alternative, source of compressed air may supply pre-combustion gases to combustion chamber directly. Source of compressed air may be used to supply pre-combustion gases to a compressor if, e. This may be the case under operating conditions such as, e. Source of compressed air may also be used to control the pressure in the combustion chamber relative to the pressure in e. In one embodiment, turbocharger may include, e. In an alternative embodiment, source of compressed air may be recharged between uses.
Engine performance may also be enhanced by electrically assisting turbo-charger for better airflow control. An electrically assisted turbo-charger may improve low engine speed operation by providing combustion air to the engine such as, e.
Electric motor may be used to turn compressor if, e. Electric motor may be used to control the pressure in the combustion chamber relative to the pressure in e.
Engine performance may also be enhanced by Including a variable geometry turbo-charger. A variable geometry turbo-charger improves low engine speed operation. In one embodiment, also shown in FIG. In another embodiment, also shown in FIG. Waste gate may be used to control the pressure in the combustion chamber relative to the pressure in e. Having wastegate as an option allows the use of a smaller turbine housing or a smaller turbine wheel and may also allow higher airflow at lower engine speeds and torques.
Use of a smaller turbine housing or a smaller turbine wheel may further result in improved turbo-charger response during transient engine conditions. A drawback of using a smaller turbine housing or a smaller turbine wheel, on the other hand, may be excessive turbine boost and speed at higher engine speeds and torque. Higher turbine boost may produce higher cylinder pressures and increase thermal loading of the aftercooler, as well. Opening the wastegate may also reduce turbine speed, consequently prolonging the lives of the compressor and the turbine and reducing thermal loading of aftercooler A spill valve may be positioned between pump chamber and discharge nozzle for controlling a rate of fuel injection to combustion chamber The spill valve shown in FIG.
Spill valve has a first position providing a maximum fuel injection rate when spill valve plunger is closed FIG. In operation, fuel may be fed to the fuel injector by the fuel supply line The fuel-injecting plunger pressurizes the fuel , and the spill valve controls the spilling of fuel above the fuel-injecting plunger When the spill valve is completely open, fuel is spilled at a rapid rate, and no increase in the fuel pressure occurs.
When the spill valve is partially closed, the fuel above the fuel-injecting plunger may be pressurized, but due to the slight spilling action the spilling effectively reduces the cam velocity. When the spill valve is completely closed, the fuel may be completely pressurized and the discharge nozzle opens. This spilling action may be electronically controlled, and may occur, for example, during the first and critical five to ten crank degrees of fuel injection. This may be especially important for urban operation.
It should be appreciated, however, that the electronically controlled spilling action may be performed at any time, and it is not strictly confined to the first five to ten crank degrees of fuel injection.
