ADAS and AV technologies are going to disrupt the entire transportation industry, as we know it, with a profound impact on human life. They promise to enhance human lives by providing a safer and much more accessible transportation ecosystem to all of society. However, to deliver on all of its promises, they need to be at least as good as a ‘good’ human driver. Therefore, they need to be very safe and robust, with the ability to perform in a variety of driving scenarios, and be very secure, being immune from any external cyberattacks. Hence, such technologies need to be tested very extensively. However, from various studies, it has been found that, to declare a full AV as good as a human driver, the AV will be required to drive more than a billion miles on real roads, taking tens and sometimes hundreds of years to drive those miles, considering even the most aggressive testing assumptions.

The objective of this project is to design of gas mixer venturi as per IS4477 and simulation of dual fuel (Diesel-CNG) engine for performances parameters to examine the BSFC using GT-suite. In present work; a 59 kW diesel engine of 18.5 compression ratio has been converted to operate on dual fuel (Diesel-CNG) keeping same compression ratio with improved fuel economy. Natural gas is an excellent fuel. Its combustion and emission characteristics are superior to any other realistic competing fuel. There are advanced technologies like closed loop lambda control system and lean combustion are incorporated in the engine to achieve the performance targets. In the initial stage; experimental testing is conducted for base diesel engine on engine dynamo for performance parameters. Experimental testing data and design data's of base diesel engine are used as input in GT-Suite to predict the performance of the base diesel engine.

This paper discusses experimental outcome of port fuel injected engines operated on gasoline mode and LPG mode. Eight Passenger car PFI engines were tested by using computerized engine data acquisition and control system on gasoline mode and LPG mode. Objectives of this experimental study were 1) To establish generic performance trend for group of newly introduced gasoline/LPG passenger car bi-fuel engines in Indian market. This trend has been established. 2) To compare performance of one sample engine in gasoline and LPG mode. This performance has been compared from performance characteristics curves in both modes. 3) To establish methodology to compare and contrast the performance of various types of Gasoline/LPG passenger car engines. This methodology has been established for a group of engines. 4) To define new normalized figure of merit suitable for the performance comparison of passenger car engines. A parameter power per unit displacement has been defined.
