A test of noise reduction in an internal combustion engine by the use of a light-weight and anti-corrosion muffler. 2nd report. Heat resistant epoxide resin muffler for a 1.5L gasoline engine.

This paper presents the internal combustion engine power generation using syngas from the updraft biomass gasifier as a fuel. 3 types of fuel such as Golden shower tree wood chip, charcoal, and gasohol 91 were tested for the engine running. The experiment was performed on July 25-26, 2017 at Faculty of Industrial Technology Vallaya Alongkorn Rajabhat University Pathum Tani Thailand. Data on the performance of the engines fueled with producer gas and gasohol 91 is presented. The experiment was carried out by using a four-stroke 13 HP gasoline engine coupled with a generator as a load in producing electricity. The carburetor was modified for fuel gas running by loading 7 kg/batch of Golden shower chips and charcoal for syngas producing and the engine performance was measured. The results showed that, the engine power was 110.125 W, 115.425 W, and 128.038 W, while using a golden shower chip, charcoal, and gasohol 91 as the fuel, respectively. The generator efficiency is 80% therefore the generator power reduces 20%. The test indicated that golden shower chips could produce higher quality of syngas than charcoal but the engine power has less power than fueled with gasohol 91.

Thermodynamic Processes

All known automotive concerns and institutes specialized in ICE problems have worked to identify the relationship between the compression ratio of ICE and its efficiency and to investigate the nature of thermodynamic processes taking place in ICE. Numerous experiments have also been carried out to increase the compression ratio of ICE. But these works had a negative result. Building on this negative result, ICE theory adopted, as axioms, claims that the compression ratio of a gasoline engine cannot be higher than 14. That the most effective compression ratio of the diesel internal combustion engine is in the region 17-23, and at the compression ratio 40 it becomes zero. Experts and theorists were so established in the correctness of these provisions that at this stage the slightest attempt to question them caused a sharp reaction.

Abstract An analytical method is presented for the thermodynamic analysis of an automotive internal combustion engine with the characteristics of the commercial BMW N54 spark-ignition model. A 3-L displacement volume, six in-line cylinder, four-stroke gasoline engine is considered with two 0.57 bar boost pressure turbochargers and an air-to-air intercooler. Thermodynamic, fluid flow, and heat transfer phenomena are mathematically analyzed to provide results on the chemical composition of the cylinder gases, on their temperature and pressure, on the amount and properties of the residual exhaust gases, on the volumetric and mechanical efficiencies, on the specific fuel consumption, the torque and brake power output, the thermal efficiency, and the energy balance of the engine. The analysis provides results in very close agreement with the actual torque and brake power characteristics reported by the BMW manufacturer.

Steam Plant

The possibility of sustained flight by heavier-than-air-machiaes was fully recognised during the last century by those who had studied the aerodynamic problems involved and it was realised that its accomplishment awaited only the development of a prime mover of sufficiently light weight.Of all the known forms of prime mover, the internal combustion engine alone held out any promise of fulfilling the conditions necessary .for sustained flight, namely, light weight not only of the engine itself but also of the fuel it consumes. Early attempts had, however, been made to fly with steam, propulsion and it is of interest to note that the very remarkable and cleverly-designed steam plant employed by Sir Hiram Maxim in 1894 was actually very considerably lighter per h.p., even including the boiler and condenser, than the petrol engine used successfully some nine years later by the Wright Brothers.
