Yamaha’s diesel motorbike ready; Patent and Images describe how

Yamaha’s diesel motorbike ready; Patent and Images describe how

The age of diesel engines for motorcycles, some believe began (and ended) with the Royal Enfield Bullet Taurus. It needed a backbone made of steel, and teeth of titanium to bare the vibrations and harshness of riding one. If you were driving near one, you needed ear plugs.

While diesel engine have evolved to such a level that it terrorizes the gasoline engine’s existence, its application has began widening. Now Yamaha has put its head out and it could be the first manufacturer to offer diesel engines of 2-wheelers commercially.

Yamaha has filed patents for a new family of motorcycle-size turbodiesel engines in both inline-four and twin-cylinder layouts.

Obviously a diesel engine is heavy and big. Packaging needs to be thought out and that’s what these patents deal with. The arrangement of the different parts is matched to a 2-wheeler’s structure, for example the intercooler is placed above the engine saving space and the bike’s fuel tank is moved backwards.

Toyota Corolla Altis 2.0 Dual VVT-i launched in Indonesia

Toyota Corolla Altis 2.0 Dual VVT-i launched in Indonesia

What is the Corolla Altis Dual VVT-i about?

The Indonesian market has a firm relation with Toyota vehicles and Japanese manufacturer has dropped yet another variant of the best selling Corolla Altis in the market.

The 2.0 Dual VVT-i variant features only a new radiator grille, but only when you open the bonnet you find the rational explanation to the word “Dual” on the badge.

Who the heck is Dual VVT-i? Is this the same case as Hero Honda Splendor and Splendor+ with fuel tank stickers seperating the two?

Generally, the term dual on a car is implied as a dual-fuel engine that is capable of handling fuels of different nature. But not this one though.

The Dual VVT-i is two VVT-i meaning both the inlet and exhaust valves obtain variable valve timing capabilities. The regular Corolla Altis, like the one sold in India is equipped with VVT-i only for the intake valve, so only the volume of mixture entering the engine can be controlled by altering the duration of valve in open condition.

According to you, what could be the advantages?

With the Dual VVT-i technology, the flexibility is enormous, and the regulated delay and advancement of the exhaust valve timing improve throttle response and minimize fuel wastage and emissions brought about by it. At lower revs, the valve shuts sooner and at higher revs it is otherwise. The driver will be able to feel the change.

Fiat introduces Multiair technology at the Geneva Motor Show

Fiat introduces Multiair technology at the Geneva Motor Show

If you have a love for the engine, the word Multijet should make your heart beat faster. Well, it’s the award winning engine that’s doing all the thermodynamics under the bonnet of the Swift, Palio, Indica Vista and 500. GM could use this engine in the future, and all of the Indica’s and Indigo’s in the future will latch on to this technology, not to mention the ever-enlarging Fiat line up.

A technology that will compliment Fiat’s already-fuel efficient engines, has been introduced by Fiat at this year’s Geneva Motor Show. It’s termed Multiair technology is similar to a VTEC or VVTi, which deals with variable valve timing for better engine response and lower fuel consumption/emissions.

Indian Couple claims to have cracked the zero emissions engine

Indian Couple claims to have cracked the zero emissions engine

Pollution levels are rising every day and maneuvering through my city traffic with windows rolled down in the morning rush is like negotiating a metro sewer without a gas mask. Smoke, in all colors and smells enter my car, so strong that attempts by several car perfume manufacturers went futile.

This innovation-

* Kanishk Sinha, 30, and his wife Lipika, 25, have been the brains behind the Jasper engine

* An engine that doesn’t use petrolium fuel or batteries to produce power

* Does not give rise to any of the harmful emissions that a petrol or diesel engine would

What we have here is a totally environment-friendly engine that can be used for several application. It’s called the Jasper Engine.
