“…Thus, the author suggested using chicken fat for low and partial loads only. Having increased the load, the engine worked as a normal compression ignition engine [30]. Increasing the content of the chicken fat in diesel led to a decrease in the exhaust gas temperature.…”

This article presents a change in the indicators of a compression ignition (CI) engine by replacing conventional diesel fuel (D100) with pure chicken fat (F100) and mixtures of these fuels. Mixtures of diesel and fat with volume ratios of 70/30, 50/50 and 30/70 were used. Research of the fuel properties was conducted. In order to reduce the fuel viscosity, blends of fat and diesel were heated. The experimental research was conducted at different engine loads with exhaust gas recirculation (EGR) both off and on. The conducted analysis of the combustion process revealed a significant change in the rate of heat release (ROHR) when replacing diesel with chicken fat. Chicken fat was found to increase the CO2 and CO emissions, leaving hydrocarbon (HC) emissions nearly unchanged. Having replaced the D100 with diesel and chicken fat mixtures or F100, a significant reduction in smoke and nitrogen oxide (NOx) emissions was observed when EGR was off. When EGR was on, the smoke level increased, but the blends with chicken fat reduced it significantly, and the increased fat content in the fuel mixture reduced the NOx emissions. The engine’s brake specific fuel consumption (BSFC) increased while the brake thermal efficiency (BTE) decreased, having replaced conventional diesel with chicken fat due to differences in the fuel energy properties and the combustion process.

“…At high load, the engine shows difficulties controlling auto-ignition, resulting in a pressure increase that causes increased noise, detonation and possible engine damage. The two main criteria for setting limits are combustion stability and engine detonation: when combustion becomes unstable or when detonation becomes unacceptable, the operation is no longer feasible [14] [15]. Since HCCI combustion is determined by chemical kinetics, direct control methods for ignition initiation are difficult, however, there are a number of indirect methods that have the potential to control the auto-ignition and heat release rate of HCCI combustion [3] [10] [11] [16].…”

An experimental bench was designed and developed to carry out experimental tests of a Diesel cycle engine using gasoline as fuel. The engine (originally a diesel cycle) was fitted with different devices to run in HCCI mode. These modifications did not affect the engine's original condition, which can be returned to diesel mode at any time. Instrumentation was set up to measurement the temperature (exhaust gases, inlet charge inlet, lubricating oil), pressure (intake air, gasoline inlet, combustion chamber), torque, rpm, air flow and fuel flow. The engine was subjected to different operating conditions and control parameters to study and analyze the effects of engine speed, air-fuel ratio and mixture temperature (air-gasoline). The results indicate that higher temperatures or amounts of fuel cause an earlier ignition phase, which would have a direct influence on the beginning of combustion. The results also indicate that, by increasing the amount of fuel and varying the inlet temperature, more useful energy is generated until reaching the limit of the detonation zone. Small gains in combustion efficiency translate into significant energy savings, also reducing exhaust gas pollution levels.

“…Karuppan et al conducted the experiment on homogenous charge compression ignition engine fuelled with chicken fat oil biodiesel. Based on the analysis, the engine operated with blended biodiesel offers high peak pressure and higher heat release rate than neat diesel fuel [8]. Regarding emission, Verma et al conducted experimental investigations on diesel engine operated with roselle biodiesel-diesel blend.…”

Plastic is a resilient, chemically inert, lightweight, and low-cost material. It sticks around in the environment for more than hundred years, threatening nature and spreading toxins. The current study deals with the use of waste polymeric materials and de oiled cake for the production of liquid oil and its blend on the performance and emission characteristics of diesel engine. The tests were conducted in an engine fuelled with diesel and four distinct blends such as 5% (B5), 10% (B10), 15% (B15), and 20% (B20), respectively. The liquid oil was produced by co-pyrolysis of neem de oiled cake (NDC) and waste polystyrene (WPS) in 1 : 2 blend ratio. The raw pyrolysis oil and its different blends were tested for their physical and chemical characteristics in order to find their suitability. Brake power (BP), brake thermal efficiency (BTE), brake-specific fuel consumption (BSFC), emissions of carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) are used to assess the performance of the engine. The experimental results reveal that BTE at all blends is lower than diesel at all loads and the BSFC increases with increasing blend ratio and falls with increasing engine load. At higher loads, the deviation of performance and emission values from baseline diesel up to B10 is very small. It is found from the results that the liquid oil derived from NDC and WPS up to 10% blend will be the promising additive for fossil fuels.
