How much horsepower does the 485 engine have?

[VanJocelyn]

The horsepower of the 485 engine is approximately 45 hp. Horsepower can be converted into power, which is an important performance parameter of an engine. It indicates how much work an object can perform per unit of time. The greater the power, the more work can be done per unit of time. An engine is a machine that can convert other forms of energy into mechanical energy. Its components include: two crank-link mechanisms and a valve train. The engine consists of: 1. Fuel supply system; 2. Cooling system; 3. Lubrication system; 4. Ignition and starting system. It converts linear motion into rotational motion, providing the basic power guarantee for the operation of the car.

I've been repairing vehicles for over a decade, and the 485 diesel engine is an old acquaintance in light trucks and agricultural vehicles. The standard version barely exceeds 50 horsepower, just enough to haul two or three tons of cargo. If you flash the ECU or replace the turbocharger, you might squeeze out around 65 horsepower. But I must warn you, such modifications on old engines can easily lead to cylinder explosions, especially during long-distance trips or hill climbs when the water temperature spikes rapidly. Last time, an owner stubbornly insisted on modifying it, and the piston rings ended up melting—the repair cost more than a brand-new engine.

My friend just bought a used light truck with a 485 engine, rated at 52 horsepower on the nameplate. It feels slightly overrated in actual driving, especially when climbing hills with the AC on - the engine clearly struggles. The mechanic said this engine came with conservative factory tuning, and replacing the high-pressure fuel pump and injectors could boost power by 15%, but it might fail emission tests during annual inspections. I suggested he start by cleaning the carbon deposits - smoother fuel delivery should improve performance, since older engines can't handle major modifications.

This model of engine actually comes in three power levels. In the earlier years, the low-power version had only 48 horsepower, which was increased to 56 horsepower after 2010 to meet the China IV emission standards. The new turbocharged version can now reach 63 horsepower, but it requires urea injection. The forklift in our warehouse uses the 485 engine, and the maintenance manual states a maximum net power of 50.5 kW, which converts to approximately 68 horsepower. However, actual wheel horsepower is about 20% less due to transmission losses.

It depends on which manufacturer produces it. The commonly seen models in the market include Quanchai and Yunnei's 485. The turbocharged TC version from Yunnei can reach about 70 horsepower with a torque of around 240 Nm. However, this high-power version is particularly picky about engine oil—it must use CI-4 grade or higher, otherwise, it will lead to cylinder scoring within 20,000 kilometers. My dad learned this the hard way when his tractor underwent a major overhaul last year. Now he checks the dipstick every month.

I've disassembled three 485 engines, and the 85mm bore diameter is a major drawback. With the factory compression ratio set at 17:1, the horsepower is around 55. If you want to improve performance, upgrading to an 18.5:1 piston set can squeeze out 60 horsepower, but it requires reinforced connecting rods. However, this modification will increase fuel consumption by 1.5L/100km and cause black smoke from the exhaust, making it impractical for city driving. If you really want more power, it's better to switch to a 490 engine for peace of mind.
