Tip & How-To about Mercedes-Benz E-Class

Engine operation

A review of engine operation:

In order to function properly an engine requires mechanical integrity along with a combination of air, fuel and a well timed spark. Engine operation is governed by an Electronic (Power) Control Unit/Module (ECU/ECM/PCM)or Engine Management System (EMS) that receives signals from a variety of sensors and in turn supplies air, fuel and timing appropriately. To reduce the impact of engine emissions on the environment the ECU also operates a number of emission control actuators and these too are monitored by sensors
Fault diagnosis can be helped by viewing the engine in several states: (i) starting;(ii) warming up or 'open cycle'; and (iii) as running at normal operational temperatures or 'closed cycle'. Most errors, and frequently the most inconvenient, relate to the start, or rather, failing to start process, closely followed by an engine that otherwise behaves normally but shuts down with little warning. When sensor signals indicating conditions outside normal operational parameters are sent to the ECU, the respective errors codes (DTCs Diagnostic trouble codes) are recordedand the 'check engine light' (CEL) or 'malfunction indicator light' (MIL) is illuminated on the dash board. Reading these error codes indicates the system in error and helps diagnose the fault.
The sensors and actuators included in this general guide are an amalgam of the ones found on many of today's cars.This is not to say that every car will have the full set of sensors or the exact layout as discussed here. Cars vary from manufacturer to manufacturer and technical developments also occur over time introducing new sensors whilst making older ones obsolete. NEXT 1) Air: From atmosphere to engine

my truck wont always start bought a new battery so thats not it auto zone said not getting enough air when it starts


Is the battery turning over the engine properly or is it barely cranking over? The main function of a battery is to provide the power to turn the engine over until the engine starts, then it's only function is to help regulate the voltage in your system along with the alternator. Will the truck start when you hook it up to jumper cables? If the engine is turning over properly and the truck not starting, the battery is not the problem. You then need check out other things. For a gasoline engine to run, it requires three things; fuel to burn, compression in the engine and a spark at the right time to ignite the fuel. You must have all three for it to work.

Hi


As far as the review says the mileage should not falter since it is new as you said. However

These are the causes of a poor mileage in a car:-


Poorly Inflated Car Tires

Car tires that are improperly inflated create significant road resistance and drag on a moving car. A car engine has to work harder to propel a car forward due to this increased tire/road resistance. This resistance chips away at a car's gas mileage.


Dirty Air Filter

A dirty air filter impedes air flow into a car's engine, a process that disrupts normal engine combustion and makes it less efficient. This causes a reduction in both engine performance and gas mileage.


Bad Spark Plugs

Spark plugs are responsible for igniting a car's air/fuel mixture, an event that causes a mini explosion inside a car's engine cylinders. Bad or dysfunctional spark plugs don't fire, or ignite, properly; thus, they affect engine combustion negatively, which in turn negatively affects gas mileage.


Bad Oxygen Sensors

For a car to be at its most fuel efficient, its oxygen sensors, small and electronically operated, automatically adjust a car's air/fuel mixture and have to be functioning properly. Bad oxygen sensors cause abnormal air/fuel mixture ratios, a condition that results in poor gas mileage and poor vehicle performance.


Leaky Fuel Injectors

A car's fuel injection system is responsible for injecting precise amounts of fuel into a car's engine cylinders, where it is combined with air and ignited. For a car to perform properly, a specific amount of fuel has to be injected by each fuel injector into each engine cylinder. A leaky fuel injector wastes fuel by leaking it outside the engine and reducing the amount of fuel that makes it into the engine. This results in wasted fuel and reduced gas mileage.
It is suggested to start with a code scanner to find out if there are any stored fault codes in your car.

no turn signals,dash doesn't work


First check the fuses for signal/hazard lights; From Park Lamp Relay, check the fuse 2 and fuse 3 (15 AMP)

Second, check the "flasher" for signal lights;

For last, review your Turn Signal Swtich:
  1. Disconnect and isolate the negative battery cable from the battery.
  2. In order to disarm the air bag system, allow the system capacitor to discharge for at least 2 minutes, before performing any removal procedures.
  3. Remove the upper and lower steering column shrouds.
  4. Disconnect the electrical connector from behind the combination switch.
  5. Remove the mounting screws securing the combination switch to the steering column adapter collar.
  6. Remove the combination switch from the vehicle.

To install:
  1. Install the combination switch to the steering column adapter collar. Tighten the combination switch mounting screws.
  2. Reconnect the electrical connector to the combination switch.
  3. Install the upper and lower steering column shrouds and tighten the retaining screws.
  4. Reconnect the negative battery cable and check all functions of the combination switch for proper operation.
