EURO IV 6DLD-22E4

The CA6DLD-22E4 employs a proven 6-cylinder in-line layout with direct injection, representing decades of diesel development experience. Built around a 112 × 145mm bore and stroke combination, the engine displaces 8.57 litres and delivers power with the consistency that commercial operators demand. This configuration has been refined through extensive testing to provide reliable service across varying operating conditions and load requirements.

The engine utilises four valves per cylinder, allowing excellent gas exchange efficiency. This arrangement works alongside the precisely engineered combustion chambers to extract maximum energy from each fuel charge whilst keeping emissions within regulatory limits.

Performance Specifications

Power & Torque Delivery:

• Rated Power: 261kW at 2100 rpm
• Net Power: 258kW at 2100 rpm
• Maximum Torque: 1500 Nm between 1300-1500 rpm

The engine’s broad torque curve ensures excellent drivability across the operating range, providing robust pulling power for heavy-duty applications. The peak torque delivery at relatively low engine speeds enhances fuel economy whilst reducing mechanical stress on drivetrain components.

Fuel Economy & Efficiency:

• Fuel Consumption: 192 g/kWh (SCR configuration) / 194 g/kWh (EGR configuration)
• Smoke Opacity: ≤0.3 m⁻¹
• Noise Level: ≤96 dB(A)

These figures demonstrate the practical benefits of the engine’s well-developed fuel systems and combustion technology. Fleet managers can expect reduced fuel bills and fewer service interruptions, whilst still meeting environmental regulations.

Advanced Technology Systems

Fuel Injection Technology: The engine uses common rail fuel injection technology, which allows precise control over fuel delivery timing and quantity. This system supports multiple injection events during each combustion cycle, leading to cleaner burning and better throttle response than older injection methods.

Forced Induction System: The turbocharged and intercooled configuration maximises power density whilst maintaining excellent fuel economy. The intercooling system reduces intake air temperature, increasing charge density and preventing knock under high-load conditions.

Emission Control Technologies: Two distinct emission control pathways are available:

• SCR (Selective Catalytic Reduction) route for maximum efficiency
• EGR (Exhaust Gas Recirculation) route for simplified installation

Both systems ensure full compliance with EURO IV emission standards, incorporating sophisticated aftertreatment systems that reduce nitrogen oxides, particulate matter, and other harmful emissions to well below regulatory limits.

Physical Specifications & Installation

Engine Dimensions:

• Length × Width × Height: 1285 × 820 × 1160mm
• Dry Weight: 870kg (SCR version) / 900kg (EGR version)

The compact dimensions and reasonable weight facilitate installation in various commercial vehicle platforms whilst maintaining excellent power-to-weight ratios.

Quality & Manufacturing Excellence

Built at FAW Jiefang’s established Wuxi Diesel Engine Works, the 6DLD-22E4 comes from a facility with more than 70 years of engine manufacturing experience. The plant maintains ISO 9001 quality standards and uses modern production methods to ensure each engine meets specification requirements.

The facility spans 670,000 square metres and employs over 3,500 people, making it one of China’s larger diesel engine production centres. With annual capacity exceeding 600,000 engines, the facility has the scale to meet consistent supply demands.

Applications & Versatility

The EURO IV 6DLD-22E4 excels in numerous commercial applications:

• Heavy-duty trucks and commercial vehicles
• Coach and bus applications
• Industrial power generation systems
• Marine propulsion installations
• Construction equipment powerplants

This versatility stems from the engine’s robust design, excellent power characteristics, and reliable operation across diverse operating conditions.

Environmental Responsibility

Meeting EURO IV emission standards demonstrates FAW Jiefang’s commitment to environmental stewardship. The engine’s advanced emission control systems significantly reduce:

• Nitrogen oxides (NOx) through SCR or EGR technology
• Particulate matter (PM) via sophisticated filtration
• Carbon monoxide (CO) through optimised combustion
• Hydrocarbon (HC) emissions via precise fuel management
