The energy consumption throughout the world has been increasing every day. The fossil fuels are the main energy source for automobiles. The increase in the usage rate of fossil fuel proves to be a major source of greenhouse gases and air pollution. On the other hand, in the form of waste plastic, a good source of energy is dumped without any usage. Since plastic materials are non-degradable, this leads to a considerable problem in solid waste management. Waste plastic oil can be obtained through pyrolysis process of waste plastic. The physical and thermal properties of the waste plastic oil (WPO) are near to the diesel fuel. The waste plastic oil can be directly used as a fuel for unmodified CI engine. This reduces plastic waste, and it acts as a viable source of energy. In this experiment, different blends such as WPO20, WPO40, WPO60, WPO80 and neat waste plastic oil are used as a fuel in the CI engine. The performance and emission results have shown that WPO20 produces better results than the other blends of waste plastic oil. So, this blend is used for further research. Many researchers have analysed the engine characteristics using WPO as a sole fuel in CI engine, but no research has been done so far with WPO as a fuel in LHR engine. LHR engines have various advantages such that they may increase the adiabatic flame temperature, reduce the heat loss, which in turn increases the brake thermal efficiency, and reduce HC and CO emissions. The LHR engine is tested with WPO20 as a fuel, and its performance and emission values are compared with a conventional diesel fuel engine. The engine vibration is found to be reduced while using LHR engine rather than the conventional diesel fuel engine. The experiment results from LHR engine show improved BTE and reduced emissions, such as CO and UBHC, while there is a slight increase in NOx.

A growing interest in extracting oil from waste plastics has converged with rising demand for petro-fuels and issues in disposing of waste plastics. The characteristics of pyrolytic oil produced from plastic wastes were compared to diesel and found to be sufficiently similar to be used as an alternative fuel. In this paper, an attempt has been taken to enhance the combustion properties of waste plastic oil blended diesel following dispersion of nanographene particles. The performance and emissions of a single-cylinder direct injection compression ignition engine with compression ratios ranging from 16:1 to 18:1 was evaluated using 50, 70, and 100 ppm by using 50, 70, and 100 ppm by mass of nanographene dispersed in 20% waste plastic oil blended diesel without any engine modification. By supercharging the engine with nanographene at various compression ratios, the performance of a 20% plastic oil blended diesel is compared to that of a neat diesel. The brake thermal efficiency of 20% plastic oil blended 100 ppm graphene dispersed diesel fuel increased by 1.16% at a compression ratio of 17:1 when compared to diesel. The CO, HC, NOx emissions also dropped significantly by adding 100 ppm nanographene to WPO as compared to the other combinations of fuels.

Despite a number of efforts to evaluate the utility of water-diesel emulsions (WED) in CI engine to improve its performance and reduce its emissions in search of alternative fuels to combat the higher prices and depleting resources of fossil fuels, no consistent results are available. Additionally, the noise emissions in the case of WED are not thoroughly discussed which motivated this research to analyze the performance and emission characteristics of WED. Brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) were calculated at 1600 rpm within 15%–75% of the load range. Similarly, the contents of NOx, CO, and HC, and level of noise and smoke were measured varying the percentage of water from 2% to 10% gradually for all values of loads. BTE in the case of water emulsified diesel was decreased gradually as the percentage of water increased accompanied by a gradual increase in BSFC. Thus, WED10 showed a maximum 13.08% lower value of BTE while BSFC was increased by 32.28%. However, NOx emissions (21.8%) and smoke (48%) were also reduced significantly in the case of WED10 along with an increase in the emissions of HC and CO and noise. The comparative analysis showed that the emulsified diesel can significantly reduce the emission of NOx and smoke, but it has a negative impact on the performance characteristics and HC, CO, and noise emissions which can be mitigated by trying more fuels variations such as biodiesel and using different water injection methods to decrease dependency on fossil fuels and improve the environmental impacts of CI engines.

Currently the Biggest threat to environment and public health is Air Pollution which is caused by emissions of hydrocarbons, nitrogen oxides, carbon oxides and sulphur oxides by burning of fossil fuels. In recent years consumption of fossil fuels by various factories has rapidly increased that has let for the search of alternative fuels. These fuels are also known as non-conventional fuels which can be used as a substitute for conventional fuels Algae oil is one of the promising potential sources of bio-fuels generated from microbes. It is generally preferred because it is sustainable and environment-friendly oil which have numerous advantages. So the algae oil has used for performance and emission test on a diesel engine. The blends have been made for testing B5, B10. In which 5% of methanol has mixed and others are raw algae oil (5% for B5 and 10% for B10) and Diesel (90% for B5 and 85% for B10). The Kirlosker Engine with 6.97 HP (5.2KW)@1500rpm is used for Performance analyzing. Parallels AVL emission analyzer and smoke detector were connected with the exhaust of the engine. All values of gases were displayed and compared.

One of the possibilities to reduce diesel fuel consumption and at the same time reduce the emission of diesel engines, is the use of alternative gaseous fuels, so far most commonly used to power spark ignition engines. The presented work concerns experimental research of a dual-fuel compression-ignition (CI) engine in which diesel fuel was co-combusted with CNG (compressed natural gas). The energy share of CNG gas was varied from 0% to 95%. The study showed that increasing the share of CNG co-combusted with diesel in the CI engine increases the ignition delay of the combustible mixture and shortens the overall duration of combustion. For CNG gas shares from 0% to 45%, due to the intensification of the combustion process, it causes an increase in the maximum pressure in the cylinder, an increase in the rate of heat release and an increase in pressure rise rate. The most stable operation, similar to a conventional engine, was characterized by a diesel co-combustion engine with 30% and 45% shares of CNG gas. Increasing the CNG share from 0% to 90% increases the nitric oxide emissions of a dual-fuel engine. Compared to diesel fuel supply, co-combustion of this fuel with 30% and 45% CNG energy shares contributes to the reduction of hydrocarbon (HC) emissions, which increases after exceeding these values. Increasing the share of CNG gas co-combusted with diesel fuel, compared to the combustion of diesel fuel, reduces carbon dioxide emissions, and almost completely reduces carbon monoxide in the exhaust gas of a dual-fuel engine.
