What Is Engine Braking? How Does The Cooling System Work?

We are here with another interesting topic to help you understand some complex functions of the engine in simple terms. As is the case with every article of this series of Automobile Technology Content, we try to pick up technical topics related to inner burning engines or car engineer and sample to make you understand the process in childlike terms. We know some of the car enthusiasts do love to know everything about their vehicles and are looking for some chopine to get answers to their queries and we try to address those topics in this section. nowadays ’ s topic is a very interest one and something that people experience every time they drive their cars. It is called Engine brake. besides, everyone must have heard the parole coolant as well. We will try to understand these two concepts in this blog mail today. sol, let us dive straight into it.

Engine Braking

The concept of engine brake is actually very dim-witted to experience but a act unmanageable to learn about. A lot of people ask about the importance of locomotive brake and if it is harmful for the locomotive. We will try to discover the causal agent of the engine brake and its consequence on the engine. We will besides see what function do coolants play in locomotive brake. besides learn : Types of Turbos – VGT, Twin-Scroll, Twin-Turbo, Sequential, E-Turbo !


When you are driving in second gear for case, and you let go of the accelerator pedal you experience a little jerk and the car starts to slow down. This is something that everyone must have experience during driving. In childlike terms, this is called Engine Braking. In other words, when your cable car is in gearing and the accelerator pedal is released and the car decelerates without the lotion of brakes, engine brake is happening. How does it slow down ? This can be explained by taking into consideration gasoline engines. When the accelerator pedal is released, the strangle valve closes. This means that there is no/very little consumption of fresh air into the cylinder. This, in act, means that the piston, while going down into the suction stroke, pulls against the vacuum. This is actually what causes the engines to slow down over time.

The piston pulling the vacuum leads to the car slowing down happens every time you release the accelerator pedal point regardless of which gear you are in. In fact, you will experience this greater with 1st and 2nd gears in comparison to 3rd or higher gears. This is because the infection is driving the engine in this subject, which is the reverse of what happens by and large. Since the gear ratios of the first and second gears are higher the effect is more pronounce and you get a stronger tug adenine soon as you release the natural gas pedal. In a way, the gears/transmission is holding the car and not the brakes. In mountains, even you are going downhill for a long clock, it is preferred to use engine braking rather than actual brakes for that long. This is because over continuous long custom, brakes get heated up a lot and the phenomenon of bracken languish starts to appear. besides understand : What is variable Valve Timing and Lift ? How do these affect efficiency and performance ? This is when the cases of brake bankruptcy happen. The principle of brake is to convert the kinetic energy into estrus energy and release it outside the fomite. however, over a certain sum, the heat generated can not be dissipated easily and the efficiency of the brakes is affected badly. In comparison, the engine is designed to take and process a lot more estrus than the brake compartment. therefore, the heat generated by the engine brake can actually be handled by the cooling system of the engine. The cooling system of contemporary cars is very sophisticate and can take a fortune more pulsate. It has been tested in extreme conditions over long periods of time. This is the most reliable method of hotness waste in a vehicle. Let us now transit into the cool system in depth. besides learn : What is engine Knock ? What are its consequences ?

Cooling System

As explained before, the cooling organization is responsible for the inflame profligacy from the locomotive. It is long-familiar that inner combustion engines produce a fortune of estrus. This is because the air-fuel mix is actually ignited and burn inside the cylinder of the locomotive. There are actual explosions happening inside the cylinder of the engines within a fraction of milliseconds. These explosions are what cause the piston to move down and beget power. therefore, there is a lot of heat inside the cylinder. Hence, the cooling systems are engineered to remove all that inflame from the engine efficiently which is why the coolants are used. besides read : How does OBD ( on-Board Diagnostics ) function ?


Coolants are additives that are added to the water to be used inside the engine to aid the cool system of the vehicles. The coolants are special compared to using regular body of water in that body of water produces steam and expands under hot conditions. On the other hand, it freezes and becomes hard during highly cold conditions. Both of these scenarios can occur at any time during the operation of cars. Hence, water is not suitable to use as a coolant. The coolant has the properties of lowering the freeze luff and increasing the boil point so that a broader window of temperature is available for the engine to operate under. This means that the water and coolant assortment will not boil at 100-degree Celcius but at a higher temperature and it will not freeze and 0-degree Celcius but at a much lower temperature. This enables the engines to work even in harsh and extreme weather conditions efficaciously. besides read : What are catalytic Converters ? How do they reduce emissions ?

That is besides the reason why engine brake is more useful for long descents compared to using the normal brakes in a fomite. The coolant runs throughout the engine to cool down the components and is connected to a radiator. The coolant gathers heat from all sorts of areas from the engine and releases it inside the radiator and gets cooled again. In this way, the coolant keeps running in a circuit and the temperature of the engine operation is maintained at the craved value. The coolants are of different colours so that they are well recognizable if they leak from somewhere. These are the functions of a coolant inside a cylinder. We hope that you are clear about the serve of engine brake in the car and would want to try to use it on the road. besides, now you know the function of the cool system along with the coolant inside the cylinder.
