Turbochargers

 Project Summary

• A turbocharger, turbo, is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber.
• It was invented Alferd Buchi in 1885.
• A turbocharger, turbo, is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber.
• Turbochargers are commonly used in passenger cars to obtain greater power output from a given engine size. The compact nature of a turbocharger means it is often a more space-efficient solution for increasing power output than increasing engine displacement. As an example, the turbo Porsche 944's acceleration

Belts, chains, shafts, and gears are common methods of powering a supercharger, placing a mechanical load on the engine. For example, on the single-stage single-speed supercharged Rolls-Royce Merlin engine, the supercharger uses about 150 horsepower (110 kilowatts). Yet the benefits outweigh the costs; for the 150 hp (110 kW) to drive the supercharger the engine generates an additional 400-horsepower, a net gain of 250 hp (190 kW). This is where the principal disadvantage of a supercharger becomes apparent; the engine must withstand the net power output of the engine plus the power to drive the …show more content…
In contrast to supercharging, the primary disadvantage of turbocharging is what is referred to as "lag" or "spool time". This is the time between the demand for an increase in power (the throttle being opened) and the turbocharger(s) providing increased intake pressure, and hence increased

    A diesel engine runs on a compression ratio which is much more higher than a petrol engine. In layman terms, it means that more air in the air fuel ratio which goes in the combustion chamber. Since diesel engines work on the compression ignition aspect as opposed to spark ignition petrol engines, diesel tends to burn the complete fuel in the chamber. Hence diesel engines are more fuel efficient than petrol ones. Diesel engine delivers more torque than a petrol engine A gas engine first mix fuel-air together and compresses and then it ignites it with the spark.…

    Back in the 80’s and 90’s diesel powered vehicles were infamous for their loud, smelly, and jittery engines. However, today’s diesel powered engines are significantly more quiet, more comfortable to drive, and with new technological advances, they aren’t throwing out black smelly fumes from their tail pipes thanks to newer catalytic converters. Diesel engines are more preferable today because they are superior fuel savers, last much more longer, and have a higher power output. A diesel engine is known for good fuel mileage and is more preferable today because they save a lot of fuel. Chuck Schifsky states, “Diesel fuel has a higher energy density than gasoline.…

    Do you want a vehicle that is good on fuel, reliable, and has power? Diesel vehicles are good on fuel, because they are good for about 300,000 miles, and provide more power. They are more reliable because they run off of compressed air and their engine parts are built stronger than traditional gas engines parts. Everyone should own a diesel vehicle over a gasoline vehicle because diesels are more fuel efficient, have more power, torque, and more reliable. Diesel engines provide more power using less fuel compared to gasoline engines.…

    An aircraft propulsion system must achieve two things. First, the system should be able to produce enough thrust that it must be equivalent to the drag on cruising airplane. Secondly its thrust should be able to exceed the drag on the airplane so that it can accelerate. The greater the excess thrust the faster will plan accelerate. Some aircrafts like airliners or cargo planes use high bypass fans or turboprops as they require higher fuel efficiency which is achieved by accelerating large mass of gas by a small amount.…

    This makes a diesel engine simpler than a gasoline engine(“Not Just for Trucks Anymore: Why Modern Diesels Are More Popular than Ever”). Gasoline engines are considered to be like a racehorse because they are high strung, fiery, and fast while a diesel engine is considered to be like a workhorse because they are slower, stronger, and more enduring(“The Pros and Cons of Diesel Engines”). The amount of fuel entering the engine will reduce as the amount of air entering the engine reduces. Engine speed will not increase past the point where all of the available oxygen is burned by the fuel by increasing fuel intake. However, in diesel engines, there is no restriction on the amount of air going into the engine.…

    The higher the compression a car’s motor can produce in the cylinders, the greater the power it can get out of each stroke of the piston. This makes it necessary to have fuels the can handle higher compression without auto-igniting. the higher the octane rating, the more compression the fuel can handle.…

    You also have centrifugal superchargers. Superchargers are forced induction power adders driven off the engine using gears or belts which substantially requires lots of horsepower from the engine to drive them, but they also return more power than they consume to offset their negatives to a positive. Supercharges are the easiest way to add power to many gasoline engines because they bolt on fairly simply and only require new belts and air piping to set them up. You will have to increase injector flow rates and fuel pumps, and the fuel map to use them as designed but they will return massive power for their…

    Abstract:In today’s automobile world it is a great desirable challenge to build an engine having more power generation & less fuel consumption,which are desired parameters for the increased efficiency of the engine. For getting more power engine needs more fuel and if less fuel consumption is needed the power transmitted will be less. In conventional engines the heat energy using is 30% of produced energy and the remaining energy nearly 70% is going as waste. That means, to get more power from engine the fuel resources are wasting by wasting the 70% of produced energy,if less fuel consumption rate is desirable the more power generation should be sacrificed. Present innovation namely 4 stroke engine with 2power strokes is introduced in order to overcome these problem ,The piston will execute 2nd power stroke without using gasoline fuel.…
