Automotive engineering

Automotive engineering is a special kind of vehicle engineering. It helps people design, build, and run motorcycles, cars, and trucks.

Engineers use many different skills to do this work. They use mechanical, electrical, and software engineering to make vehicles work. They even study safety to keep people protected. This field is very research intensive. This means engineers use math models and formulas to solve problems. They follow a vehicle from its first idea to the final production stage.

Making a vehicle involves several important steps. First, engineers design and develop the parts or the whole vehicle. Next, they fabricate, or build, those parts. Finally, they test everything to make sure it works well.

One big job is safety engineering. This is the study of how vehicles act during a crash. Engineers use computer simulations called finite element analysis to see how a car deforms. They also use crash-test dummies to see if airbags and seat belts work. They test for things like front impacts and how a car handles a rollover.

Engineers also look at how a vehicle feels and sounds. They study NVH, which stands for noise, vibration, and harshness. They listen for rattles or squeals. They also feel for vibrations in the seat or the steering wheel. Some NVH is bad, like a loud rattle. Other NVH is good, like the tone of an exhaust. They also check fuel economy, which is how far a vehicle goes on its fuel. They must also measure emissions to check for gases like carbon dioxide and nitrogen oxides.

Many different experts work together in this field. Development engineers make sure all the systems work in harmony. For example, they balance engine power with fuel economy. They might choose a 1.4 L engine instead of a 5.4 L engine to save fuel. Manufacturing engineers focus on the factory side. They design the machines and tools to build parts quickly. They use methods like Six Sigma and Kaizen to make production better. They also use design for manufacturability to make sure parts are easy to build.

Automotive engineering links many things you see every day. Modern cars use dozens of electronic systems for comfort and control. These systems manage the brakes, the steering, and even the lights. You might also use an infotainment system to listen to music. Even the way a car shifts gears is part of engineering. Engineers study how a driver feels when a transmission shifts. They want the ride to be smooth and the car to be durable. This ensures the vehicle lasts a long time even in harsh conditions.
