Advanced Engine Technologies

Common Rail Fuel Injection System The engine incorporates state-of-the-art common rail technology, delivering precise fuel metering across all operating conditions. This system ensures optimal combustion efficiency whilst reducing noise levels and exhaust emissions. The high-pressure injection system operates at pressures exceeding 1,600 bar, enabling superior fuel atomisation and complete combustion.

Turbocharging & Intercooling A sophisticated turbocharging system maximises power density whilst maintaining excellent fuel economy. The integrated intercooler reduces intake air temperature, increasing volumetric efficiency and power output. This configuration delivers strong low-end torque characteristics essential for commercial vehicle operations.

Emission Control Systems Available in two emission control configurations:

• SCR (Selective Catalytic Reduction): Utilises AdBlue injection for superior NOx reduction
• EGR (Exhaust Gas Recirculation): Employs cooled exhaust gas recirculation for emission control

Both systems ensure full EURO IV compliance with NOx emissions well below regulatory limits.

Performance & Reliability Features

Robust Engine Block Construction The cast iron engine block features reinforced cylinder bore linings and cross-bolted main bearing caps. This construction methodology ensures exceptional durability under high-load commercial operations. The cylinder head utilises advanced metallurgy for superior heat dissipation and longevity.

Advanced Cooling System An efficient cooling system maintains optimal operating temperatures across diverse ambient conditions. The system incorporates a high-capacity radiator, thermostatically-controlled cooling fan, and strategic coolant flow routing throughout the engine block and cylinder head.

Lubrication System A full-flow lubrication system with high-capacity oil pump ensures consistent oil pressure delivery to all engine components. The system includes an efficient oil cooling circuit and replaceable full-flow oil filter for extended service intervals.

Operational Excellence

Noise & Vibration Control Advanced engine mounting configurations and internal balancing reduce noise levels to ≤95.5 dB(A). This achievement ensures operator comfort whilst maintaining neighbourhood-friendly operation during urban deliveries.

Service & Maintenance Designed for straightforward maintenance access, the engine features strategically positioned service points. Extended service intervals reduce operational costs whilst maintaining peak performance throughout the engine’s operational life.

Fuel Economy Performance Optimised combustion chamber design and advanced fuel injection timing deliver exceptional fuel economy. The engine’s broad torque curve allows drivers to maintain efficient operation across varying load conditions and terrain.

Applications & Compatibility

This versatile powerplant suits various commercial vehicle applications:

• Medium to heavy-duty lorries (16-26 tonnes GVW)
• Urban distribution vehicles
• Regional freight operations
• Municipal service vehicles
• Coach and bus applications

The engine’s compact dimensions and standardised mounting points ensure straightforward integration into existing vehicle platforms whilst providing scope for new vehicle development programmes.
