Is it necessary to clean carbon deposits on piston tops?
1 Answers
It is absolutely necessary to clean them. If left uncleaned, the consequences include reduced power, increased fuel consumption, louder noise, and higher pollution levels in exhaust emissions. Below are expanded explanations of the causes of carbon deposits: 1. Poor fuel atomization: Diesel engine piston tops are prone to carbon buildup. The main cause is poor fuel atomization by the injector, which results in inadequate mixing of fuel and air, incomplete combustion, and ultimately carbon deposits on the piston top. 2. Excessive engine oil: This is mostly due to excessive clearance between the piston and cylinder, or incorrectly installed piston rings, especially trapezoidal rings. If installed in the wrong direction, they can scrape oil towards the piston top.
