What are the reasons for the loud engine noise in the Trumpchi GS4?
2 Answers
The reasons for the loud engine noise in the Trumpchi GS4 are: 1. Insufficient engine oil or cold engine oil not yet warmed up, leading to inadequate oil pressure; 2. Presence of impurities or excessive dirt in the engine oil, preventing effective regulation of oil pressure; 3. Mechanical interference in the engine or blockage in the lubrication circuit. The Trumpchi GS4 is a compact SUV under GAC Motor, equipped with a 1.5T turbocharged engine delivering a maximum horsepower of 169 PS, a maximum power of 124 kW, and a maximum power speed of 5000 rpm. It features a MacPherson independent front suspension and a multi-link independent rear suspension.
Having driven manual transmission cars for many years, I'm quite sensitive to engine sounds. The increased engine noise in the Trumpchi GS4 is commonly caused by insufficient or aged engine oil. Engine operation requires lubrication - when oil levels drop, friction between pistons and bearings increases, naturally leading to more noise. It could also be due to cylinder gasket leaks or valve leakage causing unstable compression ratios, resulting in knocking sounds. Worn or loose drive belts can also create abnormal noises. I've encountered similar situations before - first check the oil dipstick yourself and top up with new oil if the level is low; if that's not the issue, then visit a professional shop to inspect the seals. For routine maintenance, change the oil more frequently and use higher-grade oil to reduce such problems. If neglected for too long, increased noise will also affect fuel consumption - the gains won't outweigh the losses.
