The YC4D20 2-liter diesel engine was jointly developed by GYMCL and AVL Powertrain Engineering. It produces 60 kW/L (80 hp/L) of power for SUVs/MPVs/N2 light-duty trucks and buses that are shorter than 6 meters. This engine uses 4 valves per cylinder, double overhead camshafts, high-pressure common rail injection technology, an electric EGR valve and variable swirl intake system.

A redesigned 400-horsepower (298 kW) YC6MK engine for on-road trucks provides enhanced low-speed torque improving stability when using high-speed gears. In addition to a reduction in fuel consumption, the engine’s noise level has also been reduced by more than 3 decibels providing superior comfort.

The model YC4S-48 which was upgraded from the YC4S engine for the high-end, light-truck market. This model targets mid- and high-end, on-road vehicles with a load capacity between 5-8 metric tons. It generates 88-110 kW (118-148 hp) power using a common rail system paired with EGR, DOC and POC technologies.

GYMCL also introduced its second-generation hybrid engine, model YCHPT II, to address the growing customer demand for advanced hybrid engines. The engine adopts plug-in systems to charge the vehicles’ batteries, and it features an upgraded gearbox with an interchangeable 5-speed automatic and manual system. This hybrid engine meets the national energy vehicle policy conditions set out in the Chinese government’s 12^th Five-Year plan, qualifying it for energy subsidies.

For the construction equipment market, two new engines were developed and launched to meet the EPA Tier 3 emission standards. The new model, YC6G220L-T31 series, replaces the 5 metric ton loaders’ current 10-liter standard displacement engine with a 7.8-liter engine. This engine features a turbocharged intercooling system and an electronically controlled fuel injection system to enable quick adjustments to the engine’s power and torque.

Additionally, the new diesel engine model YC4FA45-T30 series targets hydraulic excavators and it features a mechanical rotary pump, with a faster response and low fuel consumption. This model meets the EU S3A or EPA Intermittent Tier 4 emission standards, and it has been awarded the e-mark certificate allowing for marketing into the European Union.

To further improve its position in the marine and power-gen engine markets, GYMCL launched the YC6CL1035L-C20 engine for low-speed engine applications. This engine is lightweight, fuel efficient and it is adaptive allowing for different configuration options.

GYMCL provides a wide array of light-duty, medium-duty and heavy-duty diesel engines for construction equipment, trucks, buses and cars in China. GYMCL also produces diesel power generators, which are primarily used in the construction and mining industries. In 2012, GYMCL sold 431,350 diesel engines and is recognized as a leading manufacturer and distributor of diesel engines in China.
