Is it normal for a Jianghuai Refine to have engine vibration without cylinder misfire?
2 Answers
Jianghuai Refine experiencing engine vibration without cylinder misfire is abnormal and requires prompt inspection and repair. Below is a detailed introduction about automotive engines: 1. Overview: The automotive engine is the device that provides power to the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems, among others. 2. Others: Common gasoline and diesel engines belong to reciprocating piston-type internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston motion and outputting power externally. Gasoline engines feature high rotational speed, lightweight, low noise, easy starting, and low manufacturing costs. Diesel engines have a high compression ratio, superior thermal efficiency, and better economic and emission performance compared to gasoline engines.
I've repaired quite a few JAC Refine models. Engine shaking without cylinder misfire is definitely abnormal—don't believe anyone who says it's normal. This type of vibration is commonly caused by ignition system issues, such as worn spark plugs or ignition coils. Even if all cylinders are firing, uneven ignition causes shaking. Another possibility is uneven fuel supply due to carbon-clogged injectors or a dirty fuel filter. Engine mount rubber deterioration is another culprit—cracked mounts transfer engine vibrations directly to the chassis. Prolonged neglect affects fuel efficiency and driving stability. My advice: start with simple checks—inspect spark plugs and fuel system first. If unresolved, visit a professional workshop to test engine mounts. Addressing this early ensures smoother, safer driving and extends vehicle lifespan.
