Look, no clutch Multi-speed transmission changes gear without interrupting torque Who Transmission specialist Zeroshift has devised a multi-speed gearbox for electric vehicles (EVs) that needs no clutch: a damper inside the gear hubs and electronic control of the motor make ratio changes seamless. Having more than one gear ratio and the ability to shift without interrupting torque means the motor runs at higher efficiency, extending range and batteries’ life expectancy by up to 10%. Technology Development of the concept is under way using Zeroshift’s proprietary gear-shifting system. The innovation could enable manufacturers to downsize EVs’ electric motors, keeping them running longer at the medium loads and speeds where peak efficiency of more than 95% is possible. For drivers, that could mean more performance, greater range and longer lasting batteries. Zeroshift’s concept prevents any torque interruptions during ratio changes and does not require a clutch, issues that have so far d

What is DTSi? The DTSi (Digital Twin Spark ignition) technology from Bajaj could potentially revolutionise motorcycling in the country. The company may well want to replicate the technology in its other engines as well. This technology, which is also being patented by Bajaj Auto, boosts the performance of the engine, while simultaneously cutting emissions. The DTSi technology incorporates twin sparkplugs at either ends of the combustion chamber for faster and better combustion. Single sparkplug meant slower burning of the air-fuel mixture and sub-optimal combustion chamber characteristics. This is the heart of the new technology from Bajaj. But, its benefits are fully realised only after it is combined with a computerised direct ignition (CDI) system and new generation throttle response system. The digital CDI in the new Pulsar, which features an advanced eight-bit microprocessor handles the spark delivery. The programmed chip's memory contains the optimum ignition timing for any g

The six-stroke engine is a type of internal combustion engine based on the four-stroke engine, but with additional complexity intended to make it more efficient and reduce emissions. Two different types of six-stroke engine have been developed since the 1990s: In the first approach, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air as the working fluid for the additional power stroke.[1] The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. There are two power strokes: one with fuel, the other with steam or air. The currently notable designs in this class are the Crower six-stroke engine, invented by Bruce Crower of the U.S. ; the Bajulaz engine by the Bajulaz S.A. company of Switzerland; and the Velozeta Six-stroke engine built by the College of Engineering, at Trivandrum in Ind

Solar-powered refrigerators are most commonly used in the developing world to help mitigate poverty and climate change. By harnessing solar energy, these refrigerators are able to keep perishable goods such as meat and dairy cool in hot climates, and are used to keep much needed vaccines at their appropriate temperature to avoid spoilage.  The portable devices can be constructed with simple components and are perfect for areas of the developing world where electricity is unreliable or non-existent. [1] Other solar-powered refrigerators were already being employed in areas of Africa which vary in size and technology, as well as their impacts on the environment.  The biggest design challenge is the intermittency of sunshine (only several hours per day) and the unreliability (sometimes cloudy for days). Either batteries (electric refrigerators) or phase-change material is added to provide constant refrigeration.

The term power steering is usually used to describe a system that provides mechanical steering assistance to the driver of a land vehicle, for example, a car or truck. The power steering system in a vehicle is a type of servomechanism. For many drivers, turning the steering wheel in a vehicle that doesn't have power steering requires more force (torque) than the driver finds comfortable, especially when the vehicle is moving at a very slow speed. Steering force is very sensitive to the weight of the vehicle, and nearly so much to its length, so this is most important for large vehicles. In a vehicle equipped with power steering, when the driver turns the steering wheel, she or he feels only a slight retarding force, so a vehicle equipped with power steering can be driven by any healthy driver, even when the vehicle is being parked. This is because the power steering system furnishes most of the energy required to turn the steered wheels of the car. Most power steering systems

An anti-lock braking system (ABS, from German: Antiblockiersystem) is a safety system that allows the wheels on a motor vehicle to continue interacting tractively with the road surface as directed by driver steering inputs while braking, preventing the wheels from locking up (that is, ceasing rotation) and therefore avoiding skidding. An ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, an ABS can significantly increase braking distance, although still improving vehicle control. Stopping a car in a hurry on a slippery road can be very challenging. Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS. The theory behind anti-lock brakes is simple. A skidding wheel (where

   Tubeless tires are pneumatic tires that do not require a separate inner tube. Unlike traditional pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire so that they are forced by the pressure of the air inside the tire to seal with the flanges of the metal rim of the wheel. Traditional designs of pneumatic tires required a separate inner tube which could fail for a number of reasons, such as incorrect tire fit, friction between the tire wall and inner tube generating excess heat or puncture. Tubeless tire technology does away with the need for an inner tube thereby increasing safety. In a tubeless tire, the tire and the rim of the wheel form an airtight seal, with the valve being directly mounted on the rim. If a tubeless tire gets a small puncture, air escapes only through the hole, leading to a gentle deflation. Conversely, an inner tube could potentially burst like a balloon, leading to a rapid deflatio

The fuel cell vehicle (FCV) is the nearest thing yet to an "ultimate eco-car" that offers solutions to energy and emissions issues. FCVs are powered by fuel cells, which generate electricity from hydrogen, which is not only environmentally friendly and highly energy-efficient, but can also be produced using a variety of readily available raw materials. Thanks to these characteristics, fuel cell vehicles are ideal for achieving sustainable mobility. Therefore, Toyota is striving to make this vehicle technology widely available as soon as possible. Successful startup: -30° Celsius Extended cruising range: 830km (JC08 mode) without refueling At a steady cruising speed, the motor is powered by energy from the fuel cell. When more power is needed, for example during sudden acceleration, the battery supplements the fuel cell’s output. Conversely, at low speeds when less power is required, the vehicle runs on battery power alone. During deceleration the motor functions as an ele

In the future all electronic devices will be wirelessly powered. Small, battery-powered gadgets make powerful computing portable. The battery charger should be capable of charging the most common battery types found in portable  devices today.  In addition, the charging  should be  controlled from the base station and a bidirectional communication system between  the pickups  and base  station  should be developed. Inductive Power Systems: Inductive Power Transfer (IPT)  refers to the concept of transferring electrical power between two isolated circuits across an air gap.  While based on the work and concepts developed by pioneers such as  Faraday and Ampere, it  is  only recently that IPT has been developed into working systems. Essentially, an IPT system can be divided into two parts; Primary and Secondary. The primary side of the system is made up of a resonant power supply and a coil. This power supply produces a high frequency sinusoidal current in the coil.  The seconda
