MITSUBISHI DIESEL ENGINE

‍

The Mitsubishi Diesel Engine range is designed to provide premium levels of performance, durability and reliability with ease of maintenance. Every Mitsubishi Diesel Engine benefits from the following features and advantages:

‍

• Compact configuration to minimize installation footprint.
• Cast iron crankcase with access door per cylinder for easy inspection and maintenance.
• Quenched and tempered steel crankshaft with induction-hardened journals and pins to ensure maximum strength and low bearing wear. The crankshaft can be reground, if required, during a major overhaul.
• Wet-liner cylinder construction to ensure the bore geometry accuracy required to achieve low oil consumption. This type of construction allows easy replacement, if required, during a major overhaul.
• High performance AC8A aluminium-alloy pistons with Ni-Resist iron top ring groove insert ensure low long-term oil consumption with reduced carbon deposits.
• Individual cylinder head assemblies for easy and cost effective servicing.
• Basic consumable parts, such as fuel and oil filters, are positioned to allow easy access during routine maintenance.
• A low number of specialised tools is required to carry out maintenance activities.
• High level of commonality of parts across the Mitsubishi Diesel Engine ranges ensures ease of procurement and simplifies spare part stock control.
• Wide range of engine configurations allows choice of engine to be optimised for the requirements of each individual application.

‍

Air intake and exhaust systems

The proprietary MHIET* -designed and -manufactured turbochargers are specifically matched to the characteristics of the engine to provide maximum power output with minimum fuel consumption. Noise-reducing air inlet silencers fitted to turbochargers as standard. Exhaust manifold heat-shield plates available on various models.

‍

Option kits available

• Heavy-duty air inlet filter
• Flexible expansion joint (including counter flange)

‍

Fuel system

Mechanical pump-line-nozzle fuel system offers reliable operation with simplified diagnostics and servicing. Engine-mounted fuel-feed pump allows direct coupling to day-tank system. Standardized spin-on cartridge-type fuel filters allow simplified spare parts management.

‍

There are range of electrical and hydraulic governing systems available:

• Woodward EPG actuator and control system
• Woodward ProAct Intergrated Speed Control actuator
• Woodward PSG hydraulic governing system

‍Governing system

‍

Option kits available

• Digital setting unit for load-sharing

‍

Cooling system

Combined jacket water and intercooler coolant circuit, driven by the engine-mounted pump, enables the simplest radiator/heat-exchanger designs to be utilized.

‍

‍

‍

Option kits available

• Various radiator designs for different ambient conditions
• Pre-heater and pump system

‍

Lubrication system

Gear-driven oil pump and engine-integrated oil cooler ensures optimum performance of the lubrication system and minimum rate of wear in the engine. Easy-access filter bracket includes a bypass filter for added safety. Standardized spin-on cartridge-type oil filters allows simplified spare parts management.

‍

Option kits available

• Pre-lubrication pump system
• Manual oil drain pump

‍

Starter system

24V starter motor system and battery-charging alternator installed as standard. System sized to ensure reliable, fast starting under conditions as low as -10°C. (The use of pre-heating and pre-lubrication starting aids may be necessary under certain conditions).

‍

‍

Option kits available

• Air starter
• Redundant starter

‍

Monitoring system

High coolant temperature, low oil pressure and oil filter status alarm switches fitted as standard.
