“…This was because of the higher in-cylinder temperature in the conventional diesel engine. [27,28] At higher load, due to improvement in gaseous fuel utilization, higher incylinder temperature and extra availability of oxygen in JOME increases NOx emissions in the dual fuel engine. [35,36] Hence, at high load, the dual fuel engine emitted higher NOx compared to the conventional diesel engine.…”

The dual fuel engine shows significantly good results for brake thermal efficiency and brake specific energy consumption compared to the conventional diesel engine, at higher load. However, enhancements in NOx emissions were noticed. But it suffers with low thermal efficiency and high brake specific energy consumption, at low and intermediate loads. The application of exhaust gas recirculation (EGR) partially resolves the aforementioned problems of the dual fuel engine. In the present work, the dual fuel engine was operated with Jatropha oil methyl ester (JOME) as the pilot fuel for compressed natural gas (CNG). A comparative study has been done for various modes of operation: CNG-JOME dual fuel engine without EGR, CNG-JOME dual fuel engine with EGR, and conventional diesel engine at different operating loads. It was observed that the application of EGR improves the performance and emissions characteristics of the dual fuel engine compared to without EGR, particularly at low and intermediate loads. However, at higher loads, the use of EGR shows some adverse effect on performance and emissions characteristics, but decreased NOx emissions.

“…[3] Most research works conducted in this area used diesel as pilot fuel for CNG. [3,4,10,11,18,27,28,29] However, limited work is available on the use of biodiesel as pilot fuel in the dual fuel engine. The aim of this present work is experimentally to investigate the potential of using cold EGR in a dual fuel engine.…”

“…In this case the basic diesel engine configuration is retained and only the components of conversion system are additionally added to the diesel engine setup. As the basic engine system is unaltered, the engine can be easily switched back to operate as a standard diesel engine [3][4][5][6][7]. Karim [10] has reported that in dual fuel engines at low loads when the gaseous fuel concentration is low, ignition delay period of the pilot fuel increases and some of the homogeneously dispersed gaseous fuel remains unburned and results in poor performance.…”

The serious environmental pollution and the energy crisis all over the world has caused for development of the lower pollution and lower energy consumption automobile to become major research goal. With huge back ground, Compressed Natural Gas (CNG) is projected as the best alternative fuel for the country like India. The properties of CNG make it an ideal fuel for direct use in spark ignition engines. Conversion of any existing spark ignition engine to operate on natural gas is relatively simple with available equipment. Many spark ignition engine vehicles are successfully operating in major cities of India with CNG fuel. However CNG cannot be used as a fuel in diesel engines with ease. Since the maximum engines at present run on diesel, it will be very much useful if a solution could be found to alter the existing diesel engine with minimum modifications to run on CNG. Several researchers could attempt to run diesel engines with CNG. In the process three methods were reported to be successful to use CNG as a fuel in diesel engines, they are (i) Spark ignited gas mode (ii) Direct injection of CNG in dual fuel mode and (iii) Premixed CNG dual fuel mode. In the present work a premixed dual fuel engine was developed which can perform well for the entire range of load and experiments are carried out by varying the pilot fuel amount and studied the effect of pilot fuel amount on engine performance and emissions characteristics and determined optimum fuel injection quantity for better performance and lower emissions.

“…These are continuous feeding type digesters using biogas manure, sewage sludge, municipal solid waste, biodegradable waste as feed stock. The basic gas producing reaction in these digesters is 2C+2H 2 O=CH 4 +CO 2 [4]. Any material having cellulose as one of its constituents may be used to produce bio gas.…”

Methane was generated from cotton waste, while considering its pollution in textile industries. Cotton waste includes solid content and is rich in cellulose having a moisture content of 8.8%. It is difficult to form slurry as the waste float on water and hence an experimental set up has been made like a batch type digester and experiments were conducted with a different proposition of water with or without addition of seeding materials. It was found that cotton waste with 5 to 7.5% seeding material like cow dung or pig dung at temperatures of 30 to 35 0 C generated bio gas continuously, with a reasonably high yield from the tenth day after feeding. The gas contained rich methane and was tested in a single cylinder diesel engine as a dual fuel had the tendency to save 60% of diesel.
