⚙️ Engine Specifications

Engine Family:

Iveco C78 (Common rail diesel engine family, likely derived from F1C or similar architecture, but specific to C78 designation)

Engine Type:

Likely Turbocharged Direct Injection Diesel

Displacement:

Specific displacement for C78 is not universally defined without chassis codes, but '78' could imply around 7.8 liters or a designation tied to a specific performance output curve. Without further chassis specifics, exact displacement remains inferential. This manual covers variants 20, 30, 50, 55 which likely correlate to power outputs or specific engine configurations within the C78 family.

Power Output:

Varies by specific variant (20, 30, 50, 55). Expect a range suitable for commercial applications, likely from approximately 150 HP to over 300 HP depending on the configuration.

Torque Output:

Correspondingly high torque figures for commercial applications, essential for hauling and towing.

Fuel Type:

Diesel

Injection System:

Common Rail Direct Injection (CRDI) - typical for modern diesel engines of this era.

Emission Control:

Likely includes EGR (Exhaust Gas Recirculation), DPF (Diesel Particulate Filter) depending on Euro emission standards applicable in 2007.

🔧 Transmission

Transmission Type:

Likely a manual or automated manual transmission (AMT) for commercial applications. Automatic transmissions might be optional on certain variants.

Transmission Options:

Details on any available automatic or specialized transmissions would be within the manual.

Gear Ratios:

Specifications for gear ratios pertinent to different load and speed requirements of the commercial chassis.

Transmission Fluid:

Specific ATF or manual transmission fluid types and capacities will be detailed.

📐 Dimensions

Chassis Type:

This manual covers the C78 ENS/ENT chassis, which serves as a platform for various body types (e.g., minibuses, light commercial vehicles, specialized applications). Specific external dimensions will vary significantly based on the body builder's configuration.

Gvw:

Gross Vehicle Weight ratings will vary significantly based on the specific model variant (20, 30, 50, 55) and its intended application, likely ranging from 3.5 to 7.5 tonnes or higher for certain configurations.

🛡️ Safety Features

Crash Test Results:

Commercial vehicles of this era may not have standardized passenger car crash test ratings. The manual will likely focus on safety systems relevant to commercial operation.

Braking System:

Details on hydraulic brake systems, possibly with ABS (Anti-lock Braking System) as standard or optional equipment.

Stability Control:

Information on ESP (Electronic Stability Program) or similar systems if fitted.

Seatbelts:

Specifications for seatbelt systems.
