Howo 371: full technical sheet
The Howo 371 is a Sinotruk Howo truck fitted with the 371 hp WD615.47 diesel engine, most often as a 6x4 (10-wheeler). The number 371, written on the grille, simply indicates the engine power. Here is its full technical sheet, as a dump truck and as a tractor unit, and what you need to know about its fuel consumption.
What does "Howo 371" mean?
Sinotruk writes the engine power on the grille of its trucks: 336, 371, 380, 420… A Howo 371 is therefore a 371 hp Howo. It is not a separate model, but an engine found on several versions: dump truck, tractor unit, concrete mixer, rigid truck.
English data sheets often say "Howo 371 hp". In fact these are metric horsepower: 371 hp corresponds to 273 kW. It is one of the most common engines on classic-cab Howo trucks.
On the same cab, other power ratings exist: the Howo 336, with the 336 hp WD615.69 engine, and more powerful versions such as the 420 hp Howo A7, with the D12.42 engine. The 371 sits in the middle: enough power for a loaded site dump truck, without the consumption of a larger engine.
The WD615.47 engine
| Feature | WD615.47 engine |
|---|---|
| Type | 4-stroke diesel, 6 cylinders in line, turbo with intercooler |
| Displacement | 9.726 litres (bore 126 mm, stroke 130 mm) |
| Power | 371 hp (273 kW) |
| Maximum torque | about 1,500 N·m, between about 1,100 and 1,600 rpm depending on the data sheets |
| Emission standard | Euro II |
| Injection | Mechanical injection pump |
This Euro II engine, with mechanical injection, copes better than a modern engine with diesel of variable quality. This is one of the reasons for its success in West Africa. Check, however, that the Euro II standard is accepted for import in your country: we explain it in the 5 questions to ask before buying a truck.
Howo 371 6x4: technical sheet of the dump truck and tractor unit
The two most requested versions share the same engine, gearbox and rear axles. Here are their specifications in our catalogue:
| Feature | 6x4 20 m³ dump truck | 6x4 tractor unit |
|---|---|---|
| Gearbox | HW19710 manual, 10 forward and 2 reverse gears | HW19710 manual, 10 forward and 2 reverse gears |
| Front axle | HF9, 9 t | HF9, 9 t |
| Rear axles | HC16, 2 × 16 t, hub reduction | HC16, 2 × 16 t, hub reduction |
| Tyres | 12.00R20 | 12.00R20 |
| Fuel tank | 300 L | 400 L |
| Overall dimensions | 8.5 × 2.55 × 3.5 m | 7.0 × 2.55 × 3.1 m |
| Equipment | 5.8 × 2.3 × 1.5 m body, 8 mm floor, 6 mm sides | Fifth wheel for a 50 or 90 mm kingpin |
The full data sheets are on the pages of the Howo 6x4 20 m³ 371 hp dump truck and the Howo 6x4 371 hp tractor unit. The 371 hp engine also exists on 12-wheelers, such as the Howo 8x4 28 m³ dump truck, and on concrete mixers.
Fuel consumption of the Howo 371 truck
There is no single reliable figure for the fuel consumption of a Howo 371. It depends mainly on:
- the load: an overloaded truck uses more fuel and wears out faster;
- the terrain: a track, a quarry or a hill need more fuel than a flat road;
- the driving: engine speed, choice of gears, time spent idling;
- maintenance: air and fuel filters, tyre pressure, injector settings.
The safest way is to measure it yourself: fill the tank, note the odometer, drive for a normal week, fill up again and divide the litres by the kilometres travelled. You get the real consumption of your truck, in your working conditions. For maintenance, read our article maintaining your truck so that it lasts longer.
Strengths and points to check
- Very widespread mechanics: the WD615 and the HW19710 gearbox are known to mechanics, from Abidjan to Niamey and from Lomé to Bamako.
- Rear axles designed for sites: hub reduction helps on tracks and in quarries.
- To check: the Euro II standard for import, the exact empty weight of your version, and the condition of the clutch and injection on a used truck.
