How is the quality of Sofim engine?

Not bad. Sofim engine: The Sofim engine is the first light-duty diesel engine introduced by Yuejin from Iveco that meets Euro III emission standards. It was the earliest domestically produced engine to achieve electronically controlled high-pressure common rail technology. With a history almost as long as Isuzu's, it shares similar specifications: 2.8L displacement and two valves. Currently, the National V models are installed in SAIC Yuejin's Chaoyue series, Shangjun light trucks, and Iveco light buses. Two power segments: For National V light trucks, there are two power options. The SOFIM8140.43DV has a rated power of 92KW and a maximum torque of 320N.m, while the SOFIM8140.43BV offers a rated power of 82KW and a maximum torque of 285N.m. These figures are notable compared to current sub-2.5L engines that often exceed 100KW in power.
Veteran drivers who've operated Sofim trucks have this to say. The engine packs serious muscle—hauling two tons uphill is no sweat. Our family's van clocked 300,000 kilometers with just two oil seal replacements. The cast iron cylinder block dissipates heat well; even during summer long-hauls, the coolant temp rarely nudges the red zone. It idles with a rugged growl but smooths out on the move. Common minor issue? Fuel pump O-ring degradation causing seepage—a DIY fix with 50-yuan parts. Built tough as nails, these workhorses are construction bosses' favorites, shrugging off daily off-road pounding without rattling apart.
Having worked on diesel engines for ten years, I can share some insights. The Sofim engine has a solid structure, with a crankshaft that's 2mm thicker than common ones and copper alloy bearing shells. The turbocharger design is conservative but surprisingly durable—few of the vehicles I've serviced needed turbo replacements. The electronic control system is straightforward, with just three main circuits; diagnosing faults takes only two minutes with a scanner. Just make sure to change the diesel filter on time—I've seen several cases where clogged filters led to injector failures.
A friend used to drive an Iveco Transit, then switched to a Sofim truck. He said the acceleration is more powerful, especially at 2000 rpm where the push-back feeling is noticeable. Fuel consumption is indeed economical, less than 10 liters per 100 km for city deliveries, and only 8 liters at 80 km/h on the highway. The only downside is that parts are harder to find compared to the Transit, and regular repair shops often need to order them. The chassis feels sturdier, with no steering wheel shake over speed bumps. The engine sound is crisp, just a rhythmic 'tat-tat-tat'.
