Why can't a new car reach high speed?
1 Answers
New cars may fail to accelerate properly due to spark plug failure or improper oil pressure. Fuel supply system malfunction: The primary power source for vehicle acceleration is the engine, which operates by burning fuel. Therefore, if issues arise in the fuel supply system, the vehicle speed cannot increase normally during rapid acceleration as required. Improper oil pressure: Failure to control oil pressure, fuel injection volume, or ignition timing according to specifications. During rapid acceleration, oil pressure, fuel injection volume, and ignition timing are all critical factors. If these three elements don't meet standards, it may prevent the vehicle from achieving higher speeds. Spark plug failure: Problems with spark plugs or high-voltage wires. As essential automotive components, spark plugs generate sparks to ignite the air-fuel mixture in cylinders, enabling speed increase. Thus, when spark plugs or high-voltage wires malfunction, rapid acceleration may fail to boost vehicle speed.
