Hino Diesel Engine J05E Truck Excavator 4-Cylinder Turbocharged

Product Description:

The KOBELCO J05E engine is a 4-cylinder turbocharged intercooled, high-pressure common rail electronically controlled direct injection diesel engine designed for construction machinery. The following is a detailed introduction from the aspects of technical parameters, performance advantages, application scenarios and user reputation:

1. Core technical parameters
Basic configuration: 4-cylinder turbocharged intercooled design, cylinder diameter × stroke is 112mm × 130mm, displacement is 5.123L, dry weight is about 530kg.
Power output: rated power 131KW (178 horsepower) / 2100rpm, maximum torque is not disclosed, but it performs strongly in actual excavation equipment (such as Kobelco SK270D), bucket capacity 1.3 cubic meters, bucket digging force of 170kN (supercharged 187kN), bucket arm digging force 119kN (supercharged 131kN), maximum traction force 244kN.
Emission standards: Meet Euro 3 and non-road National III emission standards, use water-cooled EGR technology, effectively reduce PM particulate matter and NOx emissions.

2. Technical highlights and performance advantages
High-efficiency combustion system
Multi-stage injection technology: ultra-high pressure injection is achieved through the electronically controlled common rail system, and the injection timing is coordinated with the EGR (exhaust gas recirculation) device to improve fuel combustion efficiency and reduce fuel consumption.
Low emission design: EGR combined with intake temperature control inhibits the generation of nitrogen oxides; special piston rings and oil coolers are optimized to reduce particulate matter emissions.
Structural reliability
Valve mechanism: 4 valves, OHC overhead camshafts and roller-driven rocker arms are used to improve intake and exhaust efficiency and reduce compression losses.
Durability design: Strengthen key components such as crankshafts and connecting rods to adapt to long-term high-load conditions.
Adaptability optimization
Common rail system: high flow coefficient intake and exhaust port design, matching turbochargers, to achieve fast response and wide torque output.
Cooling system: modular water cooling layout, supporting compact installation of equipment such as excavators.

3. Typical application scenarios
Main equipment: widely used in medium-sized excavators such as Kobelco SK200/SK270D, suitable for 1.3-1.5 cubic bucket capacity models.
Working performance:
Power: sufficient torque in the medium and low speed range, suitable for heavy-duty operations such as excavation and hoisting.
Economy: fuel consumption is reduced by about 8%-12% compared with similar products (such as Mitsubishi 6D34), and the maintenance cycle is extended to 400-500 hours.

4. User evaluation and improvement suggestions
Highlights of user feedback
Reliability: The cumulative sales volume of the domestic excavator market exceeds 30,000 units, and the failure rate is lower than the industry average.

Fuel economy: The measured fuel consumption is about 18-22L/h (depending on the working conditions), which is about 15% lower than the previous generation of models.
Potential problems and solutions
Cold start jitter: Some users reported that the idle speed was unstable in low temperature environment. It is recommended to replace low-viscosity winter oil (such as SAE 10W-30) and check the carbon deposits on the EGR valve.
Emission upgrade requirements: For non-road National IV areas, the new regulations can be met by upgrading the ECU program + DPF (particulate filter).

5. Maintenance recommendations and costs

Maintenance cycle:
Oil/filter: Replace every 500 hours (CH-4 grade oil is recommended).
Fuel filter: Replace every 1000 hours.
Air filter: Clean every 500 hours and replace every 1500 hours.
Common troubleshooting:
Starting difficulties: Check the battery voltage (needs ≥24V) and whether the fuel oil circuit contains air.
Overheating alarm: Clean the radiator grille catkins/dust and ensure the coolant level (recommended replacement cycle is 2 years).

6. Comparison of competitive products and market positioning

Comparison with Deutz 2.9L engine:
Power: J05E has 40% higher power and smoother torque output.
Emission: Deutz models need to be equipped with an SCR system to meet National IV, while J05E can meet it through EGR.
Applicable customers: users of medium-sized excavators who pursue high cost-effectiveness and low emissions, especially suitable for fixed working conditions such as infrastructure and quarrying.
