Does Coasting in Neutral Save Fuel for Fuel-Injected Vehicles?
1 Answers
Coasting in neutral does not save fuel for fuel-injected vehicles, and more importantly, it is unsafe. With the gearshift in neutral, engine braking cannot be utilized, which accelerates the wear of brake pads and may lead to brake failure, significantly increasing the risk of traffic accidents. It is recommended that drivers of fuel-injected vehicles avoid coasting in neutral and instead coast with the gear engaged to save fuel. While a significant portion of vehicles still in operation are carburetor models, there is a fundamental difference in operation between carburetor and fuel-injected engines. Carburetor engines can save fuel when coasting in neutral, whereas fuel-injected engines achieve fuel savings when coasting with the gear engaged. Fuel injection represents a distinct type of engine, differing significantly from carburetor engines in both working principles and operational methods.
