THE ENGINE: THE HEART OF A CAR

In everyday life we ​​are used to seeing cars, buses and other means of transport. Do you know how they manage to work? How can take us everywhere wherever we go? Through a fundamental part of their structure: the engine.

RALLY LEGENDS: LANCIA DELTA INTEGRALE

Maybe it is a forgotten car now, but history doesn’t lie. The Lancia Delta  was born in 1979 as a normal, mediocre car. Giorgetto Giugiaro, a famous Italian designer and engineer, who had already projected the legendary Fiat Panda, created a new car with Lancia, that at first was unsuccessful but time has proven him right.

Between 1979 and 1987 Lancia produced 4 generations of the car, and every year the engineers introduced many upgrades of the engine, suspensions, inside quality and also of the body of the car. Actually, the legendary Delta HF integrale was born only in 1986. The last generation of Delta was the more successful. Producer added another powerful engine (in addition to the 1.3 68HP, 1.5 85HP Gasoline), the new 1.6 liter engine, supercharged by a turbo and with about 170 HP.

2-STROKE VS 4-STROKE ENGINES

You may have noticed I’m fond of cars and engines. That’s also why I’d like to be an engineer one day. Today I’m going to describe the most common types of car engines. You may have heard the terms 2 stroke and 4 stroke engines before, but do you really know all of the differences in their operation? I hope my post and the video below may help if you don't. 

The combustion engines are the most common type of engine with regard to means of transport like motorcycles, cars, busses and trucks but they are used also for small power tools like lawn mowers and chainsaws. In one of my articles in the blog I mentioned how they work but these two types have a small difference that change how they are made and used. How it works? A piston connected to the crankshaft by means of a connecting rod, flows up and down in a cylinder thanks to the force generated by the explosions of a mixture of air and gasoline. The connecting rod has the task of transforming the piston motion into a rotary motion.  But let’s talk about the differences about 2-stroke and 4-stroke engines.

ENGINES FOR THE FUTURE

One of the most important problems in the world is air pollution. Industrial  production, transports and many human activities essential to welfare and survival pollute our planet. So we need to find new ways to produce things and to travel.

In this article I’m focusing on the automotive industry and what it’s been invented to reduce emissions.
