Why Gas Turbine is better than Internal Combustion Engine?

Updated on November 29, 2010

Gas Turbine and Internal Combustion Engines,both are used to produce Power for operations of other Machines.Below are some points,which shows that the Gas Turbine is better in performance and use,than Internal Combustion Engine.

01)In winter nights,specially in cold regions,some provision has to be made to prevent Freezing in Internal Combustion Engines using Water Cooling when the Temperature of the Atmosphere falls to sub zero values.Anti-Freezer is generally used for this purpose.

There is no danger of Freezing,as Gas Turbine does not use any Water.On the other hand Gas Turbine works better if the Temperature of the Atmosphere falls below.

02)The Output from a Gas Turbine increases if the Inlet Temperature of the working Fluid decreases.At the High Altitudes where the Temperature of the Air is quite low,the Output of the Aviation Gas Turbine can be well maintained. While the Output of Internal Combustion Engine at High Altitude would decreases.

03)For the same Output,the weight per Horse Power of a Gas Turbine is about one third that of Reciprocating Piston Type Internal Combustion Engine. That is why,the Turbojet Engines are being more commonly used in Air Crafts.

04)A Low Grade Fuel can be used in Gas Turbine.In some cases even Coal and Peat have been burnt.Low Grade Fuel can not be used in Internal Combustion Engines.

05)The Fuel and Lubrication cost in Gas Turbine is lower comparing to Internal Combustion Engine.

You can add few points,if you know something about the topic.

      and Hybrid Vehicle Design Based Thereupon

      Problem Definition:

      The opening of intake and exhaust poppet valves in a traditional internal combustion engine (ICE) is achieved by the action of a camshaft. The closing of valves is usually accomplished by springs. This basic design has not changed in decades, and has the following disadvantages:

      • Wasting energy on the compression of valve springs and on the inertia of the valves;

      • Loss of power due to synchronization issues at higher RPMs, increased fuel consumption, extra pollution, and spontaneous detonation;

      • Wear and tear of valves due to their knocking on cylinders, extra noise and vibration, thereby decreasing the reliability and durability of the engine;

      • Overheating of the valves, spontaneous detonation, increasing noise and vibration, thereby decreasing the reliability and durability of the engine;

      • Excessive weight and size of the engine, its low efficiency and power-to-weight ratio, inefficient combustion and high pollutions levels;

      • The traditional 4-stroke ICE has only one “working” cycle out of the four cycles of intake, compression, power, and exhaust, which makes the engine very inefficient.

      The Wankel rotary engine, which solves some of the above problems, is the only existing production alternative to traditional piston engines, which has its share of problems, such as low time between overhauls (TBO, i.e., short life expectancy) and high fuel consumption.

      BE Technology & Solutions:

      The BE offers a conceptually new rotary ICE design exhibiting the following advantages over the existing traditional piston and rotary engines:

      • Increase in engine speed and power by at least a factor of two

      • Reduction of engine size and weight by at least a factor of two

      • Reduction of fuel consumption by at least a factor of two

      • Increase of the power-to-weight ratio by at least a factor of four

      • Reduction of vibration, noise, and air pollution

      • Reduction of the number of parts

      • Improved performance and increased life expectancy and reliability

      The BE rotary ICE allows a hybrid vehicle configuration with the Hybrid TripleDrive consisting of a rotary ICE, electric and pneumatic drives. In that case, the rotary ICE would turn an electrical generator, which would provide power to the storage batteries and to the electric motor to power the wheels, with pneumatic drive serving as an alternative to the fuel/electric drive combination and/or as power assist.

      BE’s new engine and hybrid vehicle designs are protected by four pending US patent applications. BE has a complete set of conceptual drawings and can make detailed drawings for any desired configuration of power, size, etc.

      Technical details:

      The air-fuel mixture, which does not burn completely at low RPM, cannot provide sufficient torque exactly when it is needed the most. The conventional ICE maximum torque and power are developed in the range of 3,000-5,000 RPM. During the subsequent increase of RPM, both torque and power start decreasing.

      The reasons for the foregoing are the following:

      1. Inertial loads in the crankshaft mechanism and in the cylinder valve mechanism, as well as the disruption of the phases of gas distribution; and

      2. Resistance of the intake manifold at high RPM does not allow the intake of sufficient quantities of air, which leads to incomplete combustion, resulting in decrease in torque and power, as well as air pollution by the exhaust gases.

      1. Being fully submerged in water;

      2. Low atmospheric pressure (such as at high altitudes);

      3. At extreme temperatures from -50°? to +50°?;

      Constant control and management of fuel BE rotary ICE design exhibits the following advantages:

      1. Maximum torque at minimal RPM;

      2. Stable torque and power increase in the range of 0 to 30,000 RPM;

      3. Decrease in ICE size and weight, lack of crankshaft, pistons, pushrods, valves, cams, intake manifold;

      4. Lack of gearbox and clutch; and

      5. Lack of lubrication and liquid cooling system (air cooling is used instead).

      Automatic computer control and management provides a reliable start and operation of the engine over a wide range of RPM and power under the following conditions:

      4. consumption; and

      5. Constant control and management of exhaust gases.


      The only design BE was able to find, which is somewhat related to BE rotary engine invention, was described in a patent application submitted to the US PTO in 2010. However, that particular design has a number of problems precluding it from being implemented in a production vehicle. All other rotary ICE designs were quite different from our invention. Moreover, there were no practical implementations in any production vehicles, in spite of the claimed advantages of their inventors, with the only exception of the Wankel rotary engine, which has been plagued by its share of problems, inherent in that, by now classic, design. Other reviewed non-patent prior art included scientific and popular articles with no existing practical implementations in production vehicles.
