3.6 ECU
Engine control unit, one type of electronic control unit that manages an engine's operation. Most modern engines use some type of fuel injection to deliver fuel to the cylinders.
The ECU determines the amount of fuel to inject based on a number of sensor readings. Oxygen sensors tell the ECU whether the engine is running rich (too much fuel/too little oxygen) or running lean (too much oxygen/too little fuel) as compared to ideal conditions known as stoichiometric.
The throttle position sensors tell the ECU how far the throttle plate is opened when you press the accelerator. The mass air flow sensor measures the amount of air flowing into the engine through the throttle plate. The engine coolant temperature sensor measures whether

In our project is a fumigation of gasoline in diesel engine, normally two kind fumigation is available one is a fumigation with a help of carburetor and another one using injector.
Both a methods are using gasoline fumigation but the most of research by the help of carburetor only. But in our project using injector to inject the gasoline.
The four stroke engine will run at a suction stroke the inlet air is enters to the combustion chamber doing that suction process gasoline will be injected to the path of inlet manifold. So the inlet air to reach the combustion chamber the gasoline also present.
The end of suction stroke before the injector will be stopped. It helps for to avoid the wastage of gasoline. Then gasoline and atmospheric air was fully mixed.
At the compression stroke the gasoline air mixture will be high temperature at power stroke the diesel will spray to the combustion chamber then the air+ gasoline+ diesel gives a high much power. Because the fumigation range will be created a complete combustion.
And finally the exhaust stroke smoke will low the reason belongs to fumigation is achieve the complete combustion and also it’s reducing the unburned hydrocarbon levels.

In coordination complexes the carbon monoxide ligand is called carbonyl.Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries.

Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin. A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.
The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, disorientation, visual disturbance, syncope (fainting), and
