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.

Weichai ratings follow ISO 8528 and the engines are typically rated at 40 °C ambient for export. Because many models are marine-derived, the cooling system is generous, but the altitude derate still applies from 1,000 m on turbocharged units.

Tell us the duty cycle and the maintenance capability on site. Weichai engines reward steady load and disciplined oil changes; we will specify the service kit interval to match what your team can actually deliver.

Configuration Options

Heavy blocks, practical packages

These engines were designed to run for days at a time, so the packaging favours access over compactness.

Weichai sets are built for endurance rather than density. The WP10 and WP13 units go into canopies up to about 500 kVA, and above that we move to containers with walk-in access, because the injection pump and turbocharger need room to be serviced in the field. Most export builds use mechanical or simple electronic governors, which keeps local repair realistic.

Cross Reference

Compare other engine brands

Weichai also owns Baudouin, so if you want the same engineering with a European brand story, that is the route to take.

Questions

Weichai sets, answered plainly

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

Weichai owns Baudouin. Baudouin engines are designed and badged in Europe with a premium position; Weichai-branded units are built in Weifang for volume markets.

Not the diesel models. Weichai does build dedicated gas engines, but they are a separate product line and not interchangeable with the diesel blocks.

Around 10,000 hours on prime duty with good fuel and oil. Severe-duty sites should plan on 8,000 hours.
