TH4XD-2
Flagship 4-cylinder industrial diesel
The TH4XD-2 is our flagship four-cylinder, turbocharged and charge-air-cooled (增压中冷) industrial diesel from the Ricardo-based R-series. Rated 110 kW with fuel consumption as low as 205 g/kW·h, it combines strong output for its size with the low-speed torque and serviceability the R-series is known for.

Why the TH4XD-2 is our flagship
The most capable engine in the Ricardo Power range
Combustion
Ricardo-derived direct-injection combustion for fast, clean burn and strong low-speed torque.
Charge-air cooling
Turbocharging with intercooling for stable output at altitude and under sustained load.
Load acceptance
High torque backup supports rapid load steps — ideal for standby and prime generator sets.
Serviceability
Replaceable wet liners and accessible ancillaries keep overhaul time and cost low.
