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.

This paper evaluates internal combustion engine performance parameters (Specific Fuel Consumption and engine torque) and pollutant emissions (O2, CO, and NOX), and also, provide an assessment of economic viability for operation in Amazonas state. Power supply to the communities in the Amazon region has as characteristics high costs for energy generation and low fare. Extractive activities include plenty of oily plant species, with potential use as biofuel for ICE (Diesel cycle) to obtain power generation together with pollutant emission reduction in comparison to fossil fuel. Experimental tests were carried out with five fuel blends (crude palm oil) and diesel, at constant angular speed (2,500 RPM – stationary regime), and four nominal engine loads (0%, 50%, 75%, and 100%) in a test bench dynamometer for an engine-driven generator for electrical-power, 4-Stroke internal combustion engine, Diesel cycle. Main conclusions are: a) SFC and torque are at the same order of magnitude for PO-00 (diesel) and PO-xx at BHP50/75/100%; b) O2 emissions show consistent decreasing behavior as BHP increases, compatible to a rich air-fuel ratio (λ > 1) and, at the same BHP condition, O2 (%) is slightly lower for higher PO-xx content; c) The CO emissions for PO-00 consistently decrease while the BHP increases, as for PO-xx those values present a non-linear behavior; at BHP75%-100_loads, CO emissions are higher for PO-20 and PO-25 in comparison to PO-00; d) The overall trend for NOX emissions is to increase, the higher the BHP; In general, NOx emissions are lower for PO-xx in comparison to PO-00, except for PO-10 which presents slightly higher values than PO-00 for all BHP range; e) Assessment on-trend costs indicates that using palm oil blends for Diesel engine-driven generators in the Amazon region is economically feasible, with an appropriate recommendation for a rated power higher than 800 kW.

This paper reviews the technical approach and reports on the results of ASPEN Plus® modeling of two patented approaches for integrating a gas turbine with reciprocating internal combustion engine for lower emissions and higher efficiency power generation. In one approach, a partial oxidation gas turbine (POGT) is located in the 1st stage, and the H2-rich fuel gas from POGT exhaust is cooled and fed as main fuel to the second stage, ICE. In this case, the ICE operates in lean combustion mode. In the second approach, an ICE operates in partial oxidation mode (POX) in the 1st stage. The exhaust from the POX-ICE (a low BTU fuel gas) is combusted to drive a conventional GT in the 2nd stage of the integrated system. In both versions, use of staged reheat combustion leads to predictions of higher efficiency and lower emissions compared to independently providing the same amount of fuel to separate GT and ICE where both are configured for lean combustion. The POGT and GT analyzed in the integrated systems are based upon building them from commercially available turbocharger components (turbo-compressor and turbo-expander). Modeling results with assumptions predicting 50–52% LHV fuel to power system efficiency and supporting NOx < 9 ppm for gaseous fuels are presented for these GT-ICE integrated systems.

This article presents a methodology for determining the required engine power of hybrid city buses. The vehicle’s driving cycle and its main technical characteristics were used as the initial data. The calculated change in power on the driving wheels is an intermediate result and is used to analyze the chains of energy transfer from gasoline engine to driving wheels. In this approach, a sequential type of circuit in a hybrid drive is used. A bus weighing 4 tons was considered as an example, and the calculations showed that the maximum power of the internal combustion engine should be 15.2 kW.

Working Principle

Gas Turbine is one of the machines that use the thermodynamic principle converting fuel energy to mechanical energy. It is an internal combustion engine. Also, designed to accelerate a stream of gas, which is used to produce a reactive thrust to propel an object or to produce mechanical power that turns a load. It functions in the same way as the internal combustion engine. It sucks in air from the atmosphere, and compress it. The fuel (gas) is injected and ignited (spark plug). The gases expand doing work and finally exhausts outside. Instead of reciprocating motion, the gas turbine uses a rotary motion throughout, and that is the only difference.

Oxygen Percentage

An internal combustion engine essentially requires a fuel which must have sufficient calorific value to produce enough power, and oxygen for the combustion of fuel. In normal vehicles fuel will be supplied from a fuel tank equipped with it. And oxygen will be taken from the atmospheric itself. Under normal conditions the percentage of oxygen present in atmospheric air will be around 21% of the total volume. Studies shows that by increasing the oxygen percentage in the inlet air increases engine performance and reduces emission produced by the engine.
