1. Noun maximum engine torque
is an important parameter of the engine torque performance, greater torque, the greater the “strength” of the engine output, changes in crankshaft speed is also faster, climbing vehicle slope capability, speed and acceleration start the better.
determines the maximum torque speed performance of the car, especially at a low speed acceleration. Representation from the crankshaft end of the engine output torque, torque is N · m / r / min, the maximum torque is generally present in the engine speed range, the torque with increasing speed decreased. We usually drive the engine speed in urban areas are at 2000 to 3500 rpm, which means peak torque at 4000 rpm within the engine is the most appropriate.
It is inversely proportional relationship with the engine speed, the faster the speed the smaller the torque in the fixed condition of the power, the greater the contrary, it reflects the car load capacity within a certain range. Adjust the engine torque with engine-related, including the intake system, fuel system and ignition system. But in fact the relationship is still the largest engine displacement size of the piston stroke.
