Yuchai engines are a line (27 series and more than 2000 types of motors) of power units designed to power the actuating systems of trucks, construction equipment, ships, and generators.
Yuchai internal combustion engines are structurally different depending on the specific type of equipment.
- Bus engines: YC4D, YC4E, YC4F, YC4FA, YC6G, YC6J, YC6A, YC6L, YC6MK and YC4G series with internal pump reinforcement (Euro II);
- For trucks, engines of the series are used: YC4D, YC4E, YC4FA, YC6A, YC6M, YC6J, and YC6L.
- Front loader engines: YC4D, YC4A, YC4B, YC6B, YC6J and YC6MK series.
- Forklift engines: Models YC4A115Z-T20, YC6B120-T22, and YC6A175Z-T20.
- Engines for mechanically pumped, turbocharged excavators with T2 emission standard: Models YC4D110L-T20 and YC6J160L-T20.
- Road roller engines with a mechanical pump, turbocharged/naturally charged, inter-cooled and T2 emission standard: YC6B120-T20, YC6B150Z-T21, YC6A170Z-T20, and YC6A190L-T20.
- Engines for drilling rigs with a mechanical pump, turbocharging, and T2 emission standard: models YC4D95Z-K20, YC4D80-T21, YC4D95Z-T20, and YC6MK240Z-T20.
- Yuchai civil marine engines are characterized by high combustion chamber efficiency and swirl consumption, contributing to lower fuel consumption. Yuchai's sealing technology in piston rings and valves reduces lube oil consumption. The compact size facilitates installation, maintenance, and repair.
