How to Design a Fuel-Efficient Engine?

Designing a fuel-efficient engine saves your money on fuel and keeps the environment green. So the efficiency is more important than other factors. In this article, I will discuss the details of “How to design a fuel-efficient engine”?


Design a Fuel-Efficient Engine

The design comes under the process of manufacturing. But I will discuss what can be done in your nearest showroom to save the fuel consumption rate of your engine. Changes can affect the vehicle’s aerodynamics, but the safe process can easily assist to help to figure out the problem.

Firstly define the requirement of the engine to maintain the fuel efficiency. In the vehicle, there are a lot of factors that can be noticed that the emission system, fuel chambers, and friction components can hamper the fuel rate in the vehicle.

So, read the following process, this can help you to get an idea about the design of a fuel-efficient engine.

1. Reduce Energy Loss

The engine generated 70% power losses while transmitting it to the wheels to drive the vehicle. To eliminate this problem, the FWD(Front-Wheel Drive) system was introduced. But all the moving parts need the power to rotate and also the friction generates.

All the moving parts also need engine power to lubricate themselves. If some changes can be made to move the parts with the other help then this problem can be eliminated. But the system is connected internally and all the parts need to match the timing to operate and produce power.

So the change can be made to reduce energy loss by

Minimize Friction

If the friction of the moving parts can be eliminated by the engine oil then this problem can be solved. Engine oil helps to create a thin layer of anti-friction material between the two moving parts and also helps to provide a hassle-free ride.

If the friction happens into the cylinder or in the other moving parts then the extra power needs to drive the vehicle efficiently. To push the vehicle forward then the engine needs extra power and to produce the power engine needs extra fuel.

So, use the perfect grade of engine oil and also it is preferable that one can use synthetic oil to boost the performance of the engine. Firstly, check if all the engine parts move freely in the cylinder.

Improve Combustion Efficiency

Combustion efficiency means the quality of the power generated by the combustion and the proper use of air and fuel. Combustion of fresh charge can make the vehicle run in the fuel-efficient mode and also this can help to save the parts from unwanted hesitation.

This can be done by using the proper grade of fuel, making the incoming air pure, perfect timing of spark plug, properly functioning valves, and other moving parts. The spark plug plays an important role here and the Iridium spark plug can help to assist the fresh charge to burn better.

Reduce Heat Loss

In the old models, if the engine starts in the morning then the engine needs to start a lot of time to operate. So, the heat loss makes to burn the fuel more than the optimal condition. Also, when the engine gets heated, then the burning process of fresh charge can’t be done properly.

The cooling system of the engine helps to carry all the heat from the moving parts. The combustion of the fresh charge makes a lot of heat into the cylinder and this causes damage to the internal parts. Also, this heat causes the fuel to burn before the time. This also causes excessive fuel consumption.

2. Optimize Engine Design

The design of the engine is the key factor to make the vehicle a fuel-efficient option. This design can also help to cut the air, which means it needs an aerodynamic design. All the factors of the design can impact the load of the vehicle and this load can lead the fuel to be consumed.

So, to reduce the problem and improve the design these steps can apply

Optimizing Compression Ratio

The compression ratio of a normal 4-stroke vehicle is 8:10 in petrol engines and 15:20 in diesel engines. This compression ratio also helps to find the engine is running in good condition. If the ratio changes then the engine will start knocking and the fuel loss will happen.

Using the right amount of fuel, cleaning the engine parts, and fully operating the air filter can help to reduce this issue. If some adjustments need to be made then the valve opening time or the throttle valve opening angle is the prime target member.

Lightweight the Vehicle

Excessive load needs extra drag. The load of the vehicle can be different, the excess moving parts, extra goods on the vehicle, or the extra part added with the vehicle. All these extra loads can increase the pressure on the vehicle engine and this leads to consume extra fuel.

This extra load can also hamper the vehicle damage. The tires of the vehicle, the chassis, and also the engine parts. Extra load creates extra heat and the power loss can happen. All the problems are interconnected and create problems.

3. Additional Consideration

In the additional Consideration the engine size, vehicle aerodynamics, emission control system, and powertrain system can be changed or can be optimized according to the user or the customer. But these changes can affect the overall vehicle.

All these points can be checked and done by a professional technician. The vehicle manufacturer has the equipment to change this system. So this point can be done by the professionals. Also, with the changes in the powertrain or the engine size, you need to change the other systems like sensors, actuators, the position of the bearings, etc.

So, this is against the vehicle’s nature. This point needs to be discussed that’s why it is in the article.

Designing a fuel-efficient engine is in the hands of the manufacturer. In the service centers or the garage, certain adjustments can be made to increase these chances a little bit. A car is made after analyzing the market nature and also the changes that a vehicle can make to the environment. If you need to increase the fuel-efficiency then you can check the points I have discussed in this article.

It is advisable that a properly trained technician can do this job. Please don’t try this at home.
