Fuel Injection
Fuel Injection”
Remember if you want. Your memory back to the Ford Cortina? Rarely see them now! Your grandfather or a reader of my father? Ford has sold 3 million of them in the United Kingdom. Here are some vital statistics that I can remember. Please do not cite these as they are from memory (unreliable). tree cam cam belt driven, 2-liter engine 8, the carburetor fuel delivery, ignition points. 80 to 90 hp!
Fast Forward to the Ford Mondeo Mk 4. belt driven overhead cam, 2-liter 16-valve, fuel injection, electronic ignition production any up to 150 hp. While there is much more energy, reduced emissions and low fuel consumption than the previous Ford Cortina. How do you do?
The modern ECU controlled engine electronic controls. Electronic ignition means that the ignition fuel spark is at the right time as the piston rises to near the summit of his career. It just does not happen very precise Cortina engine power because it was mechanically controlled. Many of pulleys and shaft wear and prone to error. electronic ignition is probably the biggest contribution to improved engine efficiency.
According to the electronic fuel injection. Precise control fuel in the pulse. Down with precision and in small droplets (high pressure) so that more fuel is burned in the engine and is quite moving emitted into the atmosphere as unburned fuel. The ECU (engine brain) controls the electronic fuel injection with the help various sensors "say" that the volume and temperature of air entering the engine, the report together with the throttle wide open. So look and to be aware of the sensor throttle position sensor, air temperature of air mass sensor and pressure sensor anti-knock. The sensor it (knock sensor) is used to detect pockets of air and fuel burning outside the power of the flame front normal, can damage the engine or cause "of high fuel costs.
Comparison of electronic fuel injection as I have described with delivery of fuel from the carburetor Cortina. "Carbohydrates" works fairly well, but I had to balance the air / fuel mixture, the opening the butterfly, "rich" (When the engine is cold) and "lean" mixture of air (depending on air and engine temperature) and supply of fuel to less than 4 cylinders usually a single carburetor.
No wonder he counts more efficient engines check in general. According to sources influential car car on the basis of modern electronics and mechanics. Thus, the engine management is the priority absolute when it comes to keeping a vehicle to function properly. "
Mechanically, the engine is more modern mechanized, the more you use of synthetic oil (more durable, more durable, reducing friction and increasing heat dissipation properties than oil Mineral relatively formulated) and has the great advantage of electronic ignition on their predecessors. All these and more are added to motor mechanics survive much longer than the pre-electronic units.
Unfortunately for the modern motorist, while many higher in some forms of technology can cause problems in the electronic things.
Engine Management (ECU essential sensors etc.) requires a diagnosis in cases of default or failure. To some extent this is taken from the hand only the owner and main garages dealers or expensive diagnostic teams to locate and identify the problem. Sometimes, the "failure" or an error may be caused by any something as minor as a failure of the electrical connection.
Contribute to the management of engine problems is the increasing number of sensors mounted on today's cars. There is method in what might seem crazy. The emission standards are becoming more demanding (Euro 4 and 5). The objective is to reduce g / km of CO2 and help them achieve this level of emissions (EGR exhaust) valves are now equipped and connected to the MAP sensor, and, in turn, a more sophisticated unit.
