In present commercial vehicles, the cranking torque required for a heavy duty compression ignition engine is very high. This results in higher durability and reliability requirement of cranking system components and also makes it cumbersome to implement start-stop micro hybrid feature which requires more number of cranking cycles in lifetime. Hence higher capacity starter motor and battery is being used for implementing start-stop feature. However this would result in cost and packaging issues. In order to implement start-stop feature maintaining the same starter motor and battery capacity, the cranking energy demand of the engine needs to be reduced. Studies conducted shows that the major source of breakaway torque is the work done in compression stroke during a starting cycle.

Automotive OEMs, the world over, have always given high priority for the luggage area of the vehicle. This area primarily consists of the luggage board or luggage carpet for keeping luggage and various other items. Most OEMs also provide an additional structure known as the parcel shelf or parcel tray. This part has varied usage, depending upon the OEM, ranging from holding light weight items, providing support and even as a part for covering the luggage area which looks aesthetically pleasing. In a country like India, the parcel shelf generally attracts unwanted high load storage. A majority of the solutions to this problem have been in the form of part thickness increase leading to subsequent increase in weight and cost, the two major concern areas for all auto manufacturers. A strong, but light-weight and cost effective solution is, hence, desired through innovation in design, material and manufacturing process.

The increasing variety of test configurations and requirements has encouraged the Passive Safety Department to carry out tests of greater complexity. These advanced crash tests usually involve vehicle trajectories which are not straight and cannot be performed with the usual testing system. In order to increase the testing capabilities, a new guiding system was developed to satisfy the abovementioned requirements. Several requirements for the desired system were established: 1. High reliability and robustness: to guarantee repeatability and durability in crashes. 2. In-vehicle system: to avoid the modification of the structure and without interfering in the mass distribution. 3. Electrically compatible: no electrical interference should be added in the vehicle. Based on these requirements a new vehicle guiding system was designed and developed. An in-loop processing of the images filmed by a camera enables the vehicle to follow a path marked on the floor.

In the quest towards meeting stringent emission norms as well as robust performance requirements, there is an ever growing need to continually research into and develop high calibre engines. This necessitates handling huge amounts of generated test data that monitors a multitude of variables like engine speed, combustion chamber pressure, engine load and the like. Further, in order to establish the scalar engine performance parameters like efficiency, Brake Mean Effective Pressure, Indicated Mean Effective Pressure, P-V diagram, post processing is required to be done on the measured test data that involves complex calculations like numerical integration and other mathematical operations on a grand scale. In order to meet this objective, the authors hereby showcase a knowledge based algorithm that integrates and streamlines the entire procedure from handling of the huge test data to performing all the calculations in order to arrive at the scalar engine performance parameters.

Globally, agriculture Tractor is the widely used prime mover to pull the "Implements" to do overall field operations. There are specific, custom made equipments for certain operations like Rice Transplanter, Manuare Spreader, Combine Harvester, Cotton Picker, etc to increase productivity in the agriculture farms, apart from Tractors, which just pulls implements or specially designed soil operation attachments. Due to large landholdings in rest of the world, the size and capacity of these tractors & equipments are much higher to meet the timliness in agriculture operations, which is the major decisive factor in an agriculture equipment design. Similar to other automotive products, agriculture tractors design in India also follows global designs. However, due to the narrow / marginal landholding in India it becomes mandatory to stand-off the global trend and to design specific automotive propulsion devices for agriculture applications in India which could do intercrop operations.

Speaking of industrial design in automotive engineering, safety, aesthetics (user driven aspects), ergonomics (technology driven aspects) and product economics play a key role in the success and sustenance of any auto component or product in service. One such auto component in a vehicle which necessitates equal attention from all the above said aspects is a “WHEEL”. A conventional tube type wheel for commercial vehicles is made of steel with steel side rings (multi-piece construction). In course as headway in wheel design the single piece wheels were developed which used the tubeless tires. These wheels were made available in both steel and aluminium versions. Wherein the aluminium wheels were lighter in weight than steel, aesthetically more appealing and had other significant advantages. Despite the advantages of these tubeless tire wheels, the end user had to invest for both wheels and tubeless tires to replace conventional tube type steel wheels.

The objective of this project is "Bringing Field to Lab". Normally in field, tractors are utilized for various applications like harvesting and threshing operation in a dusty environment which consists of paddy, sand, straw etc,. These dusts would affect the tractor performance and often cause problem like engine choking at severe condition. We had acquired field data on threshing from north Indian places like Jaitsar, Jalandhar where threshing done in summer at a temperature around 50°C. Also during threshing full tractor power is used through PTO (power take off) and this load fluctuates according to manual loading of paddy in thresher.

Every organization needs to effectively manage its data collection and analysis process in order to efficiently collaborate on a global scale. This paper describes a model for standardizing the data collection and analysis process developed in Caterpillar and specifically deals with two challenges in this regard: 1. A method for standardization of the nomenclature of different physical parameters measured during a typical engine test. This is essential for processing data from various facilities spread across the globe especially when we need to run them through a standard set of calculations. The process of storing and performing a given set of complex processes on the data while allowing analysts to view the steps of the processing in a transparent intuitive manner is also described in the paper. 2. Building on the first point, the paper also describes a process for performing a standard set of data quality checks on data as it is being collected.

This book covers one and a quarter century of the automobile, conceived as a cultural history of its technology, aimed at engineering students and all those who wish to have a concise introduction into the basics of automotive technology and its long-term development . Its approach is systemic and includes the behavior of drivers, producers, nonusers, victims, and other "stakeholders" as well as the discourse around mobility. Nowadays, students of innovation prefer the term co-evolution, emphasizing the parallel and mutually dependent development of technology and society. This acknowledges the importance of contingency and of the impact of the past upon the present, the very reason why The Evolution of Automotive Technology: A Handbook looks at car technology from a long-term perspective. Often we will conclude that the innovation was in the (re)arrangement of existing technologies. Since its beginnings, car manufacturers have brought a total of 1 billion automobiles to the market.

In our previous reports based on computations and fluid dynamic theory, we proposed a new compressive combustion principle for an inexpensive and relatively quiet engine reactor that has the potential to achieve thermal efficiency over 50% even for small combustion chambers having less than 100 cc. This can be achieved with colliding supermulti-jets that create complete air insulation to encase burned gas around the chamber center. We originally developed two small prototype engine systems for gasoline. First one with one rotary valve for pulsating intake flow and sixteen nozzles of jets colliding has no pistons. Next, we developed the second one having a strongly-asymmetric double piston system with the supermulti-jets colliding, although there are no poppet valves. The second prototype engine can vary point-compression strength due to the supermulti-jets and homogeneous compression level due to piston, by changing phase and size of two gears.

Abstract This paper describes the development of small rotary internal combustion engines developed to operate on the High Efficiency Hybrid Cycle (HEHC). The cycle, which combines high compression ratio (CR), constant-volume (isochoric) combustion, and overexpansion, has a theoretical efficiency of 75% using air-standard assumptions and first-law analysis. This innovative rotary engine architecture shows a potential indicated efficiency of 60% and brake efficiency of >50%. As this engine does not have poppet valves and the gas is fully expanded before the exhaust stroke starts, the engine has potential to be quiet. Similar to the Wankel rotary engine, the ‘X’ engine has only two primary moving parts - a shaft and rotor, resulting in compact size and offering low-vibration operation. Unlike the Wankel, however, the X engine is uniquely configured to adopt the HEHC cycle and its associated efficiency and low-noise benefits.
