Description
These precision-engineered parts are responsible for delivering the correct amount of fuel into the engine’s combustion chambers at the right time and in the correct spray pattern, ensuring optimal combustion, performance, and fuel efficiency.
Type and Configuration
1. Type and Configuration
The W203 uses electronically controlled, multi-port fuel injectors. Each cylinder in the engine has its own dedicated injector, ensuring precise fuel delivery.
2. Material and Durability
These injectors are typically made from high-quality metal alloys and durable plastics. They are designed to withstand high temperatures and pressures, as well as resist corrosion and wear over time.
3. Spray Pattern Atomization
The injectors are engineered to produce a fine, atomized spray of fuel. This ensures thorough mixing with air, promoting efficient combustion and reducing emissions.
4. Pressure Range
The W203 fuel injectors are designed to operate under specific fuel pressure levels, typically supplied by the vehicle’s fuel pump. This ensures consistent performance and accurate fuel delivery.
5. Electronic Control
Controlled by the engine control unit (ECU), the injectors respond to real-time inputs from various sensors. These inputs include engine speed, load, temperature, and oxygen levels, allowing precise adjustment of fuel delivery under varying driving conditions.
6. Maintenance and Lifespan
While the injectors are built to last, they can become clogged or fail due to dirt, carbon deposits, or wear over time. Symptoms of injector issues in the W203 may include poor fuel economy, engine misfires, rough idling, or difficulty starting.
