Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Web18 mei 2024 · Symptom 3: Excessive Grey Or Blue smoke from the Exhaust. If you regularly see grey or blue smoke coming from the exhaust on your car, this can be a symptom of a damaged or cracked piston. In most cases, the grey or blue smoke is caused by burning oil.
