Differences between engine 111 and engine 111EVO
| Engine 111 | Engine 111 EVO |
|---|---|
| ME-SFI 2.1 fuel injection and ignition system (Bosch) | ME-SFI fuel injection and ignition system (Siemens SIM4 SE/LE) |
| EURO2 or "D3" emission concept (code 923) | Low emission EURO3 emission concept standard (no code) For Germany certified in accordance with the "D4" emission concept |
| Oil level indicator switch (S43) | Oil sensor (oil temperature, oil level, oil quality) (B40), installed from below in oil pan |
| 2 twin-spark ignition coils | 4 single ignition coils |
| Spark plugs with copper central electrode | Platinum spark plugs, change interval approx. 100 000 km Engine 111 EVO naturally aspirated: Beru 14FGH 7 DPURX 2 Engine 111 EVO with supercharger: NGK IFR6D-10 |
| Belt drive and viscous fan clutch: with TAC/AAC electric engine/AC suction fan operated by ME-SFI control module through suction fan control module | Standard electric engine/AC suction fan operated by ME-SFI control module through suction fan control module |
| O2 sensor upstream of catalytic converter | O2
sensor upstream and downstream of underfloor catalytic converter with low emission EURO3 Engine 111 EVO naturally aspirated with "D4": O 2 sensor upstream and downstream of firewall catalytic converter |
| Air gap insulated pipes upstream of TWC | Duplex pipe (double-wall pipe without air gap) and double-wall main muffler housing for reducing structure-borne radiated noise |
| Underfloor catalytic converter | Engine 111 EVO naturally aspirated: with low emission EURO3 only underfloor catalytic converter; with "D4" firewall catalytic converter and reduced underfloor catalytic converter Engine 111 EVO with supercharger: Larger catalytic converter cross-section for reducing exhaust backpressure; with "D4" larger volume and greater rare metal content in the coating |
| Engine 111 naturally aspirated: cruise control with AT | Engine 111 naturally aspirated: cruise control with AT and MT |
| - | Engine 111 naturally aspirated: secondary air injection with electric air pump (M33) |
| Engine 111 with supercharger: Air cleaner positioned at vehicle side | Engine 111 EVO with supercharger: air cleaner positioned at engine side |
| Engine 111 with supercharger: Secondary air injection with supercharger directly downstream of exhaust valves | Secondary air injection with supercharger from air connection on throttle valve actuator (M16/6) downstream of exhaust valves |
| - | Engine 111 EVO with supercharger: Intake manifold pressure sensor (B28) for measuring charge pressure |
| - | Engine 111 EVO with supercharger: Altitude pressure sensor (B18) for measuring ambient pressure |
| Engine 111 with supercharger: Recirculated air flap actuator operated by ME-SFI 2.1 control module by means of PWM signal. | Engine 111 EVO with supercharger: Recirculated air flap actuator operated by ME-SFI control module by means of voltage signal in same way as throttle valve actuator. |
| Engine 111 with supercharger: Supercharger engageable by means of magnetic clutch | Engine 111 EVO with supercharger: Supercharger runs constantly. Bearings optimized. Muffler upstream and downstream of supercharger. |
