![]() ![]() It sounds like you’re doing that… what would happen if you got to full throttle a couple of car lengths earlier, when you had a little more steering still in the car? The classic Friction Circle is never a circle, because cars (with the exception of drag racers) don’t have enough power to keep the acceleration longitudinal g-loads high enough to make that part of the circle, a circle! The “circle” will have a relatively flatfish top.Īs a driver, I’m always asking myself if I’m using all of the grip exiting a corner, trading off cornering by unwinding the wheel to give traction to the accelerating tires. If you have a data system that can produce a g-g diagram (or gSum), you’ll see how this works in a more visual way. It may seem that you’re still cornering hard, but you’ve either straightened the wheel enough to give some pure lateral grip back to the tires for acceleration… or you weren’t using all of the grip that the tires are capable of producing. And at that moment, you must only be using 50% of the tires’s grip for cornering. So, there’s a point past the apex when you’re asking for 100% of your car’s acceleration power, but that might only be using 50% of the tires’ traction capability at that very moment. That’s not to take anything away from your car because every car is like this, to some extent. The simple answer is your car does not have enough power to need all 100% of the tires’ traction for acceleration – it can’t use all 100%. Can it be that these tires can handle more, meaning 100% full throttle in my car is really less than 100% throttle for these particular tires? I hope I am making sense!”Ī: That’s actually a great question. How can that be? I drive a Cayman GT4 with Hoosier R7 tires. So, I am 100% accelerating and still cornering. Why am I not sliding or spinning? I am a firm believer in what you said many times in your books that the tires can only do 3 things at 100% – each either accelerate, decelerate or corner and they can do a combination of the above but only up to 100%. ![]() As I am exiting certain turns, turn 1 at VIR for instance, I am at full throttle pretty much past the apex even before I fully straighten my steering wheel out. So, I am cornering at full throttle. To state it in other words, the new method and apparatus control the engine at a modest speed when the generator is unloaded or lightly loaded and increases engine speed and current frequency with increases in generator load.Q: “ I have been trying to improve my corner exit speed. The increasing step includes detecting an increase in the current to a value, determining from the look-up table the frequency corresponding to the value and increasing the speed of the engine until the frequency of the current is the frequency corresponding to the value. For some part of the monitoring step, the engine runs at a first speed, e.g., idle speed, or some moderate speed above idle speed. The governor apparatus used to carry out the method includes a microcontroller having a current and frequency look-up table embedded in it. A holding circuit incorporating the solenoid means for interrupting the circuit and thus disengaging the caliper brake to release the throttle, includes a hydraulic brake switch, a toggle switch and an ignition switch.Ībstract: A method for controlling the speed of an engine driving a generator supplying electrical current to a load includes the steps of monitoring the current, increasing the speed when the current increases and decreasing the speed when the current decreases. The caliper brake is capable of gripping a section of the throttle rod and an electrical solenoid is capable when energized of urging the brake into engagement with the throttle rod to restrict its movement. A friction device, such as a caliper brake, is provided for frictionally engaging the throttle rod to retain it in a predetermined position. But the throttle rod is not frictionally engaged to keep it in a predetermined position.Ībstract: A device is provided for maintaining the throttle of an internal combustion engine in a fixed position, the device including quick release means for the throttle. TL DR: In this article, a device is provided for maintaining the throttle of an internal combustion engine in a fixed position, the device including quick release means for the throttle. ![]()
