Zhejiang Xinchai – other nonroad diesel engines: the A498 range outside the named models, roughly 3.2-litre four-cylinder with 27 to 36 kW, federal-only certification without California
Zhejiang Xinchai Machinery, based in Shaoxing in China's Zhejiang province, builds small and mid-size diesel engines mainly for agricultural machinery, generators and light construction equipment. This page gathers the A498 range the register could not assign to a named model; the bore (98 mm) and stroke (105 mm) of the four cylinders work out to a displacement of roughly 3.2 litres.

The register lists here 8 versions with 27 to 36 kW rated output at 1,800 to 2,400 rpm, all inline four-cylinder engines with direct injection. The fuel entered is low-sulphur diesel (300 to 500 ppm), the emission stage is consistently Interim Tier 4, the power category is 19 up to under 37 kW. Maximum torque runs from 143 to 191 Nm at 1,680 to 1,800 rpm. All 8 engines are certified only for states outside California, with no separate California approval recorded.
Engines of this small power class are the standard drive for compact generators, small farm machines and entry-level light construction equipment; Xinchai positions itself here as a low-cost alternative to established Japanese brands such as Kubota or Yanmar, mainly through OEM supply to smaller equipment makers.
On a used purchase, the condition of the injection pump and glow-plug system, cold-start behaviour, the tightness of crankshaft seals and valve cover, and oil consumption all matter. Since the engines are certified only for states outside California, parts and service availability in the US is more regionally limited than with larger import brands.
