What are the reasons for difficulty in starting a gasoline engine?

[Barbara]

Gasoline engine difficulty in starting reasons include damaged carbon canister solenoid valve; low-quality gasoline; faulty intake air temperature sensor; excessive carbon buildup on intake valves, throttle valves, and pistons; and low vehicle battery power. Methods to address engine starting difficulties: Preheat during low temperatures; ensure good cylinder sealing performance; eliminate air in the fuel system; inspect all pipelines for loose connections; disassemble and clean the injector needle valve; check for short circuits in the battery circuit; add sufficient diesel to the fuel tank; change the gasoline model used. Engine maintenance methods: Use qualified engine oil; use qualified coolant; regularly clean radiator scale; periodically remove carbon deposits from the engine; replace the vehicle's air filter, oil filter, and fuel filter on time; check if the spark plugs are damaged. The car engine is the device that provides power to the car, serving as the heart of the vehicle and an energy conversion device. Its function is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder to expand the gas and push the piston to perform work. Depending on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others.
