YC12VTD1830-D30 Yuchai Diesel Engine
YC12VTD Series · YC12VTD系列
The YC12VTD1830-D30 is a 12-cylinder V-12 diesel engine from Yuchai's YC12VTD series, rated at 1220 kW prime power for generator-drive applications. With 39.2 L displacement and turbocharged, intercooled aspiration, it delivers reliable power for diesel gensets in the 900–1380 kW range.
This is a generator-drive (G-drive) rating, not a truck rating: the block, the governor and the cooling package are set up to hold a steady speed under a steady load, which is what a 50 Hz or 60 Hz alternator needs. The high pressure common rail (hpcr) fuel system on this model is what keeps the frequency steady when a large motor starts across the line.
We couple it to our own TFW brushless alternator, mount it on a common base frame and run the finished set on our load bank to 110% before it is packed. If you are comparing an engine, compare the prime figure, the torque at the alternator's rated speed, and the after-sales cover for wear parts — the Yuchai vs Cummins vs Perkins comparison walks through that comparison.

Frequently Asked Questions
What is the power rating of the YC12VTD1830-D30 Yuchai engine?▼
1220 kW prime and 1342 kW standby (ESP) at 1500 rpm, from a 12-cylinder V-12 block of 39.2 L. Prime is the continuous duty figure; standby is for outage backup only. Both come from Yuchai's own rating table for this model, and we confirm which one your load needs before matching an alternator.
Which Zhiqiang generator sets use the YC12VTD1830-D30 engine?▼
In the current catalogue the YC12VTD1830-D30 powers TFW-1200 (1200 kW). Other ratings are built to order on the same block — send the load profile and we will size the set around this engine or the next size in the YC12VTD family.
What emission standard does the YC12VTD1830-D30 meet?▼
This engine is declared Non-road T3 under China GB 20891. The tier follows the model suffix: a -D2x engine is non-road T2, -D3x is non-road T3 and -D4x is non-road T4. The emission declaration and the engine test file are issued per order, so your customs broker or consultant can review them against the destination market before the set ships.
