J05E is a 4-cylinder supercharged intercooled, high-pressure common rail electronically controlled direct injection diesel engine. It is a next-generation electronically controlled engine: the common rail ultra-high pressure injection engine is equipped with an EGR device that reduces the suction temperature and suppresses the oxygen concentration, and multi-stage injection is carried out through coordinated control to maximize fuel combustion efficiency, exert powerful medium and low-speed torque, save fuel costs, and greatly reduce PM (particulate matter) and NOx (nitride) emissions.
The GB3 model has been used in the excavator market for nearly 8 years.

Hino's unique HMMS combustion system, four-valve cross-staggered arrangement, double vortex inlet inlet inflation efficiency and distribution are guaranteed in the full speed range.
Denso's new generation of high-pressure common rail fuel injection system, accurate multiple injection, automatic compensation of fuel injection amount of each cylinder, can achieve lower engine idling, with anti-vibration, anti-heat, intelligent and other functions.
The HONEYWELL GT35 turbocharger with W/G valve is adopted, which has high efficiency and large flow, and achieves the comprehensive effect of low fuel consumption and low exhaust noise.
The engine water cooling system adopts imported temperature control proprietary technology to reduce the temperature uprush phenomenon and shorten the warm-up time by half.
The overhead cam OHC structure eliminates the need for valve pushers, and the compact superstructure and rigidity are enhanced, which improves the transient response of the valve mechanism, improves the acceleration and reduces the mechanical noise.
The cam profile is concave and the valve achieves optimal opening and closing lift movement, increased air intake, and low valve seat impact.
The cam drives the rocker arm through the roller body tappet, which significantly reduces friction and reduces fuel consumption. The rear gear transmission system improves the torsional vibration characteristics of the crankshaft system and reduces vibration and noise. The cylinder head is floating, isolating the vibration source and reducing noise.
The cylinder block is optimized into a concave and convex rib surface structure by FEA, and the dry cylinder liner is machined for the cylinder block waterway, and the runner size is more accurate and leak-free.
The integral cylinder head and the rear gear chamber are integrated casting, which increases strength, improves transmission accuracy and reliable sealing.
The new piston has a hollow wear-resistant ring, and the temperature of the first ring drops by 50 degrees, which is more wear-resistant.
Denso's third-generation direct-load ECU is powerful, interference-resistant, and vibration-resistant.
Hino's standard engine electronic control wiring harness, five layers of peripheral wrapping, waterproof grade of key connectors IP67 or above, inheritance of current single insurance, overcurrent insurance. Excellent waterproof and vibration resistance.
Modular design, fuel injection pump, air compressor pump integration, simple and compact. The inlet and outlet water, oil and gas pipelines are all metal hard pipes, which lead to centralized and fixed fast interfaces, and the piping is convenient, safe and reliable.
The powerful functional control mode of the engine ECU improves the intelligent level of the vehicle and ensures safe driving
The engine is able to get the safest working mode between starting limit, torque limit, throttle limit.
The protection items are: start protection, oil and water protection, oil pressure protection, and brake priority.
The control items include: CAN communication, cruise, idle speed adjustment, exhaust brake, warm-up, PTO mode, etc.
