Currently Automotive industry is looking for sustainable alternate of Conventional fuels. Bio diesel is an alternative fuel similar to conventional or ‘fossil’ diesel. It is produced from vegetable oil, animal fats, tallow and waste cooking oil. Bio diesel is one of the most promising fuel which can not only replace the conventional fuels but also environment friendly in terms of Greenhouse gases emission. Bio diesel can be produced from various sources and can be sustainable fuel for automotive vehicles. In this paper, efforts have been taken to convert existing Diesel engine into Bio diesel compliant engine. For making suitable for Biodiesel operation, modification in Engine Fuel system, filter and Sealing were carried out. Further Engine performance and emission testing were done and results were compared with performance and emission of same configuration Diesel engine.

A Technical Review on Performance and Emissions of Compressed Natural Gas – Diesel Dual Fuel Engine

2019-11-21
2019-28-2390
In view of the depletion of energy and environmental pollution, dual fuel technology has caught the attention of researchers as a viable technology keeping in mind the increased availability of fuels like Compressed Natural Gas (CNG). It is an ecologically friendly technology due to lower PM and smoke emissions and retains the efficiency of diesel combustion. Generally, dual fuel technology has been prevalent for large engines like marine, locomotive and stationary engines. However, its use for automotive engines has been limited in the past due to constraints of the limited supply of alternative fuels. CNG is a practical fuel under dual-fuel mode operation, with varying degree of success. The induction method prevents a premixed natural gas-air mixture, minimizes the volumetric efficiency and results in a loss of power at higher speeds.

Biodiesel can supplement petroleum product as a "perfect vitality source". It can ensure nature by diminishing CO2, SO2, CO, HC emission to an extent. The carbon cycle of Biodiesel is dynamic through the photosynthesis procedure .Plants ingest CO2, or, in other words those released by the biodiesel ignition process. Utilizing biodiesel can all the more adequately lessen the outflow of CO2, secure the indigenous habitat and keep up the environmental equalization, contrasted with the utilization of petroleum product. This paper considers the issues and gives understanding on the utilization of bio diesel in existing passenger vehicles which runs on diesel as a fuel. Because of increment in use of non-renewable energy sources viz., petroleum products are on an exponential decline. Today we have an option of electric vehicle or fuel cell based vehicles but what about the existing infrastructures of Billions of vehicles plying on Indian road. Bio diesel as a fuel solves this issue.

Methodology for failure simulation Using 4 corner 6 DOF Road load simulator of Overhanging Components: An Experimental Approach

2019-11-21
2019-28-2404
Nowadays, Road Load Simulators are used by automobile companies to reproduce the accurate and multi axial stresses in test parts to simulate the real loading conditions. The road conditions are simulated in lab by measuring the customer usage data by sensors like Wheel Force transducers, accelerometers, displacement sensors and strain gauges on the vehicle body and suspension parts. The acquired data is simulated in lab condition by generating ‘drive file’ using the response of the above mentioned sensors. For generation of proper drive file, not only good FRF but ensuring stability of inverse FRF is also essential. Stability of the inverse FRF depends upon the simulation channels used. In this paper, an experimental approach was applied for focused failure simulation of engine mount, one of such low correlation zone, with known history of failure.

In order to reduce engine development timing and cost, a numerical calculation used to evaluate valve train systems. This paper discusses the work done on kinematic and dynamic analysis of Valve Train (VT) system of a diesel engine by using 1-D Ricardo Valdyn software. The goal is to meet optimum intake, exhaust valve timing requirement, maximize valve open area and 20% overspeed requirement. Valve train model is prepared and inputs like mass and stiffness are estimated from actual weighing and finite element approach respectively. Simulation model is used for predicting valve bounce speed, valve displacement, cam-follower contact stress and strain in the rocker arm. Initially, Kinematic analysis is carried out to study the change in valve motion characteristics such as cam contour radius, tappet contact eccentricity etc. Further to this, dynamic analysis is carried out to assess forces and stresses on valve train components.

A Vibration analysis is about the art of looking for changes in the vibration pattern and then relating those changes. Vibration generates from Excitation forces due to firing, structural properties like stiffness of the engine and dynamic response. The unbalance masses percentage variation will effect on increasing in Vibration of the diesel engine with respect to Change in Speed. Inherent vibration in engine cause due to combustion is depend upon various crank mechanism, fuel or air flow, gear wheels ,unbalanced turbocharger,etc.. Individual balancing of parts and its combined effect after assembly will totally change the scenario of vibration .Shifting of vibration pattern from Lateral to Vertical plays significant role in this. Changing an eccentric mass direction gives harmonic impact in vibration. Changes in acceleration/displacement pattern with different percentage of balancing.

Development of Idling Stop System for 125 cm3 Scooters with Fuel Injection

2019-11-21
2019-28-2449
The idling stop system for scooters employs an ACG-starter connected directly to the crankshaft without reduction gears; therefore, it is possible to start the engine silently. The system is designed to stop the engine automatically when the scooter stops, and the engine restarts simply by opening the throttle. Scooters with 50 cm3 engines have already been employing the idling stop system. This system for 125 cm3 engines was developed to enlarge the application range of the idling stop system. It needs a large ACG starter because the cranking torque is higher than that of 50 cm3 engines, so the cranking torque was reduced by using a decompression device. The ACG starter was designed with a thin and large diameter construction in order to minimize the increase in engine width. The new idling stop system was developed with an integrated control of the fuel injection system and the ACG starter.

Testing Electric Vehicle sub-systems using low cost programmable electronic load

2019-11-21
2019-28-2492
The advancements in Electric Vehicles have introduced many complex sub-systems with demanding and sporadic power needs. For example, the current consumed by electric motor or bank of super-capacitors involve transients making them non-linear loads. Conventional test systems for load analysis mainly involved resistive loads where the rate of rise or fall of current was linear, falling short to accommodate the dynamic behavior of the Electric Vehicle loads. In this paper, we have proposed a low cost; yet effective electronic load that is independent of the battery voltage and can sink the current in any prescribed pattern with respect to time. The simulation results have shown the effectiveness of the hardware with respect to changes in temperature, aging and sudden input fluctuations. The implemented electronic load is interfaced to a desktop application to program the dynamic load behavior and the test duration.
