Hybrid powertrains have been on the market for more than a decade and have become one of the most successful alternative powertrains available today. More than a million hybrids are sold globally per year, primarily in Japan and the US. Some OEMs estimate that up to 80% of their light-duty vehicles may require some level of hybridization to meet upcoming CAFE regulations in the United States. Hybrids are also starting to make inroads into markets in Europe, and have recently been introduced to Chinese and Indian markets, among others. Basic information on hybrids is scattered among information sources, and is often difficult to synthesize.

Homogeneous charge compression ignition (HCCI) combustion was studied as a means of reducing PM and NOx emission simultaneously while maintaining high thermal efficiency and lower fuel consumption. An innovative low cost dual injection strategy is developed to investigate HCCI-DI combustion. This study is focused on the effect of fuel properties and cetane number on HCCI-DI combustion to understand the combustion and emission behavior of a direct injection HCCI engine using double injection strategy with blends of n-heptane and isooctane as fuel. A comparison is also made to understand the behavior and benefits of HCCI-DI combustion over the conventional combustion system. All experiments were carried out at a constant speed of 1350 rev/min and at zero, 15% and 30% of the full load conditions to avoid high knock intensity for high cetane fuel which occurs beyond this operating load condition.

Cycles to cycle variations are always a cause for concern in port fuelled SI engines. Earlier studies in this field suggest that cycle by cycle variations in the position and growth rate of flame kernel has a significant role in the cycle by cycle variations in the pressure curves. Researchers are always interested in understanding the fluid flow and combustion characteristics in a running engine to study these variations in detail. Due to its simplicity in adaptation, fiber optic spark plug enables the researchers to study the effects of charge motion on the developing flame kernel at relatively less cost and effort. In this paper 8 channel fiber optic spark plug was used to measure and understand the flame kernel development. Flush mounted pressure transducer were also installed to measure the in cylinder pressure data so as to analyze various combustion parameters.

The desire for higher fuel economy, improved performance and driveability expectations of customers from engines are gradually increasing along with stringent emission regulations set by the government. Many original engine manufacturing companies are prompted to consider the application of higher function variable valve actuation mechanisms in their next generation vehicles as a solution. The VVA is a generalized term used to describe any mechanism or method that can alter the shape or timing of a valve lift event within an internal combustion engine. The VVA allows lift, duration or timing (in various combinations) of the intake and/or exhaust valves to be changed while the engine is in operation. Engine designers are prompted to consider Variable Valve Actuation (VVA) system because of the inherent compromises with fixed valve events. The major goal of a VVA engine is to control the amount of air inducted into the engine which is a direct measure of torque.

The paper discusses a novel design of four and two stroke engines having one intake and one exhaust horizontal rotary valve. The rotary valves defines an open passage that may permit up to extremely sharp opening or closing and very large gas exchange areas. This novel design is applied to a naturally aspirated or supercharged two and four stroke engines all gasoline fueled with central direct injection and spark ignition. The engines are modeled by using a 1D engine & gas dynamics simulation software package to assess the potentials of the solution. The novel design produces much larger power densities than the traditional poppet valves revving higher speeds, with reduced frictional losses, and with larger gas exchange areas while also improving the fuel conversion efficiency thanks to the sharpness of opening or closing events.

Best fuel efficiency is one of the core requirements for commercial vehicles in India. Due to the high Diesel prices this requirement is beside reliability and durability very important for end customers when deciding for a new truck or bus. Consequently it is a central challenge for commercial vehicle OEMs to optimize the whole powertrain, hence match the engine, transmission and rear axle specifications best to the defined application. The consequent high number of possible commercial powertrain combinations of engine, transmission and rear axle specifications requests for an efficient and effective development methodology based on system simulations. With this, the most suitable powertrain specifications, meeting all end customer requirements can be ensured.

Proper sealing of engine is very important parameter in engine design. Even small amount of gas leakage from the engine can affect the overall performance of the engine during operation. There are two important factors in enhancing the efficiency of the sealing of the gasket are right tightening torque of bolts & gasket design. In this study, both the distribution of the contact pressure on the gasket, and the stresses of the cylinder head at different loading conditions, such as cold assembly, hot assembly, cold start, and hot firing, is simulated by commercial tool, based on the finite element method (FEM). The results shows that the efficiency of the sealing of the cylinder head gasket depends on the tightening torque of the hold-down bolts, without taking into consideration any thermal load resulting from the temperature distribution in the cylinder head.

With mounting pressure on Indian manufacturers to meet future fuel economy and emissions mandates—including the recently passed Corporate Average Fuel Consumption (CAFC) standards for light-duty vehicles—many are evaluating new technologies. However, to provide an economically sustainable solution, these technologies must increase efficiency without increasing cost. One promising solution to meet both current, and future, standards is the opposed-piston engine. Widely used in the early 20th century for on-road applications, the opposed-piston engine was eventually removed from on-highway applications due to challenges with emissions and oil control. Recent advancements in computer-aided engineering tools combined with state-of-the-art engineering practices have enabled Achates Power to develop a modern opposed-piston diesel engine architecture that is clean, significantly more fuel efficient and less expensive to manufacture than today’s four-stroke engines.

Scuffing is an instantaneous gear failure, where flanks are welded together under pressure and temperature at high speed conditions. This is one of the common failure modes in manual transmission. Fig: Picture of scuffing near the gear tip High contact pressures are often experienced in high density power transfer gears at the tip and the root regions. These higher pressures coupled with higher sliding velocities and frictional heat generation makes the tip and root regions in the gear susceptible to scuffing. Gear geometry, operating speed, gear material composition, surface roughness and lubricant properties influence scuffing. A balanced gear tooth design with lower sliding velocities is often chosen as an approach to avoid scuffing. However, in the current scenarios of transmissions with high power density requirements achieving a balanced gear tooth design is seldom. Lubricants with higher viscosity avoid scuffing but has adverse effects on the transmission efficiency.

The paper will deal with a new forward-looking 7-speed hybrid dual-clutch transmission for transverse applications. The new base system realizes 7 well stepped forward speeds with only 2 shafts. The space of the usually third shaft is used for the e-motor or the mechanical reverse speed. The e-motor and reverse speed integration is modular by using identical parts and a common flange on the transmission housing. The direct connection of the e-motor to the differential helps to avoid additional gear set loads and efficiency losses. Finally such modular transmissions will help to reduce development und production costs in future.

The development of an energy efficient air conditioning system for electric vehicles is an ever increasing challenge, because the cooling as well as the heating of the passenger cell reduces the cruising range dramatically. Almost always the compressor of the air conditioning system in electric cars is a scroll compressor with a separate electric motor and appropriate power electronics. However, this solution is critical in terms of the installation space, the weight and also the costs. Therefore, IAV develops innovative and energy efficient drivetrain structures for electric vehicles, which integrate the motor of the air conditioning compressor directly into the drivetrain of the vehicle. Thus it is possible to switch off the compressor motor and to use the main motor for the propulsion of the air conditioning compressor at certain driving situations. As a result the operating point of the main motor can be shifted to a better efficiency.
