Why does Isuzu use VM engines?
2 Answers
Here are the reasons why Isuzu uses VM engines: 1. Extended lifespan: The intercooled turbocharging increases output power by enhancing air density without enlarging displacement or significantly increasing weight. The intercooling process reduces intake air temperature from 120°C to 60-110°C, prolonging engine service life. The double overhead camshaft design enables separate control of intake and exhaust valves, allowing adjustable valve overlap angles for greater power output. Additionally, the VM 2.5T diesel engine features a tunnel-type cylinder block structure known for exceptional durability and extended service life, ensuring sustained powerful performance throughout its lifecycle. 2. Robust power: The current VM 2.5T China VI version delivers maximum power of 110kW and peak torque of 360N·m, with outstanding low-speed torque for excellent acceleration. It generates substantial torque output at relatively low RPMs, producing noticeable acceleration thrust. Whether during startup, acceleration, urban driving or off-road conditions, it provides composed power delivery. Although its power/torque tuning leans conservative, the engine boasts extremely high reliability and stability with affordable maintenance costs, effectively reducing long-term ownership expenses.
I'm a car enthusiast who often researches the engine usage strategies of various brands. Isuzu uses VM engines, and I think there are several key factors. VM engines are technologically mature in the diesel sector, excelling particularly in lightweight design and high torque output, which aligns with Isuzu's requirements for practicality and efficiency. Historically, the two companies have been long-term partners in global markets, allowing them to share R&D resources and production lines, saving Isuzu time and investment in developing new engines. From a market demand perspective, under strict emission standards in parts of Europe and Asia, VM engines are easier to certify, helping Isuzu expand its product line. I believe the future trend toward electrification may bring more collaboration opportunities, such as hybrid system development.
