Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
Such add-on overdrive boxes were available from the 1930s to the 1970s for cars and light trucks. Today, most petrol and diesel cars and trucks come with an overdrive transmission because of the benefit to fuel economy. [4] Overdrive is included in both automatic and manual transmissions as an extra gear (or two in some cases). [5]
The driver comes off the accelerator, the engine quickly goes into overrun but there is a short delay before the vehicle feels as though it has been shunted forwards slightly. The driver gets on the accelerator after the engine has been on overrun, there is a short delay before the vehicle feels as though it has been shunted backwards slightly.
An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
The AOD (automatic overdrive) is a four-speed automatic transmission, with the 4th gear as overdrive. Introduced in 1980, it was Ford 's first four-speed automatic overdrive transmission. The gearset design is based on the Ford "X" automatic transmissions used during the 1950s, '60s, and '70s.
At the time, warming the car in the winter made sense since it could take several minutes for the right air-fuel mix to reach the engine, without which the vehicle was at risk of stalling or ...
Delay box is a common slang term used in drag racing to describe an on-board timer which is a transbrake delay timer. A transbrake forces the race car to remain stationary at the starting line, in gear, regardless of how much engine power is applied.
In an automatic transmission vehicle, the car is equipped with a tilt sensor that, when it reaches a certain angle or greater, tells the brake system to keep the brakes clamped for a few seconds longer after the driver releases the brake. This allows time for the driver to depress the accelerator, moving the vehicle forward.
