The weight of the GW4C20A engine is 175 kg (with attachments). The engine number GW4C20A is located at the junction of the block and the gearbox. This engine has not been in production for very long, but it has proven itself quite well so far. The most trouble is caused by carbon deposits on the valves due to the direct injection system. There have been cases of turbine failure due to bent impeller or burst pipe. Complaints about excessive vibrations and very long warm-up time are also found on the forum. With frequent and sharp accelerations, the timing chain may stretch as early as 120,000 km mileage.
