Fuel and exhaust system specifications (Opel Corsa C)

General parameters

Fuel - See Specifications for Chapter 1.

Fuel tank - See Specifications for Chapter 1.

Specific fuel consumption/CO₂ emissions - See. Specifications to the Chapter "Controls and operating techniques".

Power supply system type

Petrol models - All models are equipped with a distributed sequential injection system controlled by the ECM. Injection is carried out into the intake ports of the cylinders.

Diesel models - All models are equipped with direct injection system with electronic control system Z13DT/Z17DTHC engines with common rail ("Common Rail").

Technical characteristics of the power supply system

Low pressure fuel pump type - Electric, submersible, fits inside the fuel tank

High pressure fuel pump:

• Diesel engines Z13DT/Z17DTH — Fuel injection pump "Common Rail" (without fuel distribution function)
• Diesel engines Y17DT(L) — distributor type fuel injection pump

Adjustment data

Both petrol and diesel models are controlled by electronic devices. Any adjustment of the fuel system parameters should be made only at a service station using special diagnostic equipment.
