    How is the torque curve of a gasoline engine different from a diesel?

    The diesel engine torque curve looks very similar to a supercharged gasoline engine torque curve. That made me think of another advantage the diesel engine has besides higher compression ratio, atmospheric pressure at the valve when it opens. The diesel engine is already more efficient without...

    Temperature & Pressure at Exhaust of IC Engines

    On a typical engine with a catalytic convertor the temperature of the piston typically reaches 600* while the gasses or flame temperatures reach temperatures of 2300* to 2500* in the cylinder under compression, once the gasses are no longer compressed the temperatures fall. The pressure in the...

    Are Electronic Braking Systems the Future of Automotive Safety?

    In a way the ABS system has the ability to function in such a way. Utilizing stored pressure or/and an electric pump the system can apply brakes at any of the 4 wheels without the driver touching the pedal - slow a spinning wheel (TC) or pivot the car to keep it from spinning (ESC). Full...

    Braking at high speed vs low speed.

    Hello, I am new but I have some technical knowledge of vehicles that I can share that might assist you in finding the answer. The mechanical advantage of the brake pedal is applied to the brake booster, a vacuum is stored on the engine side of a diaphragm and atmospheric pressure is allowed into...
