Both 50 Hz and 60 Hz builds are listed. Model codes carry the standby rating and, where two builds share a rating, a trailing letter.

Yuchai declares ratings to ISO 8528 at 40 °C ambient. The larger YC12 engines hold output well in heat but need the coolant circuit sized for continuous duty, so we quote the radiator separately for prime-power projects.

Sizing a Yuchai set?

Name the destination country and the fuel sulphur level you expect. Yuchai's export builds are configured around fuel quality, and the filtration package we fit for 5,000 ppm sulphur is not the one we fit for 50 ppm.

Configuration Options

Volume platform, export package

High domestic volume keeps parts cheap; the export package is what makes the set survive outside China.

Yuchai sets are assembled for export with a deliberate parts strategy: common filters, a Deep Sea controller and a locally serviceable fuel system. Small YC4 units go into canopies, YC6 units into canopies or open skids, and the YC12 twelve-cylinder engines at the top of the range into containers with remote cooling.

Questions

Yuchai sets, answered plainly

The three things buyers ask us most about this engine platform.

It is publicly listed with state-linked ownership, based in Guangxi. It is one of the largest diesel engine producers in China by unit volume.

Around 3,750 kVA using the YC12VC twelve-cylinder engine in a containerised power plant.

Most export builds are Tier 3 or China Stage II. Stage V is limited to specific models, so confirm the certificate before tendering into the EU.
