Countermeasures against Noise and Vibration in Direct Injection Diesel Engine

Article of Honda R&D Technical Review Vol.16 No.2


The newly developed 2.2L 4-cylinder diesel engine for the new ACCORD marketed in Europe employs numerous noise and vibration reduction technologies. 2nd-order vibration balancers and other technologies have been used to reduce engine noise and vibration, and optimization of pilot injection has reduced combustion noise. In addition, a principal axis of inertia type engine mounting system with torque rods has been employed, and soundproof performance of complete vehicle has been improved.
The new ACCORD using this new engine is powerful yet achieves the high quality cabin sound and low vibration levels, and has been extremely well received in the European market.
