The engine used in gasoline model cars has a bias power and torque. The aircraft model engine is biased towards the speed.
The crankcase of gasoline engines is larger, so the output torque is greater. Due to the need for a clutch, the volume is larger. The rear of the crankcase is equipped with a magnetic flywheel, which, in conjunction with the high-pressure package above, forms a self-controlled spark plug ignition system.
The airplane model gasoline engine has a smaller crankcase and a higher rotational speed with the same displacement. To save weight and eliminate the need for a clutch, the magnetic flywheel ignition system has been removed for a smaller size. Instead, a CDI electronic ignition system with an independent power supply has been adopted, further reducing both volume and weight. CDI generally receives power from batteries or uses separate battery packs for independent power supply. If the CDI is not connected to the battery, it cannot start.
Most aircraft model engine is not equipped with an electronic starter, while the vehicle model is equipped with an electronic starter. An electronic starter helps users to start their vehicle real quick. For model engines, users have to manually start the engine by manually turning the propeller. This is very inconvenient and poses potential risks. Therefore, EPHIL has developed engines with electronic starters for aircraft model engines, making the process of starting the engine simpler.
There is no commonality in lifespan, which is all related to the usage environment, user control techniques, and the quality of piston rings and cylinder liners. Of course, good usage habits and good engine maintenance can help give your engine a longer lifespan. This applies to both model car engines and model airplane engines
