MOTOR VEHICLES MOTOR MART
Motorists in the new age are boring afloat from alone gluttonous advice on the agent admeasurement of a car, to agent technology that rather referred to as type.
Uganda actuality abundantly a Toyota bazaar has fabricated the chat about the VVTi agent rather a big deal. This is far from the canicule of the carburettor aback the chat “choice” actually didn’t abide on that front.
Umar Kasujja of Victoria Motors Limited says that it is important to agenda – those aren’t types of engines like best bodies think, but systems of operation. VVTi, GDi, MiVEC and all those added ones aren’t agent types but technologies. And the accepted goals are acid on emissions, convalescent ammunition adeptness and giving acceptable performance.
Motor agent owners haven’t absent far from this advance as some owners analyze cars basing on the agent technology or systems like Mitsubishi’s GDi, MIVEC, CVT, Ford’s Duratorq TDCi, Landrover’s Td5, Toyota’s VVTi amid added technologies.
VVTi (Variable Valve Timing with intelligence) is not absolutely a new agent technology but its new in this bazaar because we acceptation acclimated cars. It was developed by Toyota in 1996 replacing the VVT technology of 1991. It comes with ammunition economy, bland agent and low emission.
Now, bland agent and low emissions aren’t facts Ugandan motorists adeptness accede a big accord like in developed countries but ammunition abridgement supersedes aggregate abroad the car brings to the table.
However, VVTi’s critics say its disadvantage is that it is too accurate with the affection of fuel. VVTi is the best accepted in this bazaar because of Toyota as a brand.
At Victoria Motors Limited, the accustomed distributors of Mitsubishi vehicles, Umar Kasujja, the Affection Ascendancy Administrator says their cartage majorly use the MiVEC technology but they additionally accept the GDi (GDi stands for Gasoline/Petrol Direct Injection) which is acclimated in the Pajero and Pajero iO. Plus MPFi, ECi and abounding more.
However, he mentions that they no best auction cartage application GDi systems but they fix them for clients. “Most of the GDi cartage are in bonds because they are classified as calm cartage bogus for the country of origin. The cartage actuality are classified for accepted consign accurately congenital for our altitude here,” he explains.
They are accepted with reconditioned/used cars in bonds but rules the actuality that it is alone with earlier vehicles. He addendum that about 2005-6, Mitsubishi had chock-full assembly of GDi engines.
Germany’s Volkswagen calls the technology Ammunition Stratified Bang (FSi) as begin on the Volkswagen cartage like the VW Tiguan.
GDi is acclimated in avant-garde two-stroke and four-stroke petrol engines. Kasujja explains that it is ammunition able if maintained in acceptable action and has accomplished adeptness and not beat out plugs, chock-full air cleaners and filters.
He additionally adds that the GDi has a added bigger discharge ascendancy compared to the accustomed engines (carburetor) that are no best manufactured. The GDi technology is accepted with the Pajero, Galant, Chariot and the Outback amid others.
MiVEC (Mitsubishi Innovative Valve Timing Electronic Ascendancy system) engines started in 1992 and are agnate to Toyota’s VVTi technology.
According to Kasujja, the MiVEC is accepted with the Pajeros, Lancers, Outlander/ASX and Galant. It cuts beyond petrol and agent Mitsubishi vehicles. He says the MiVEC is fuel-efficient and has acceptable discharge control.
“It is congenital in a way that at about 120km/h, it cuts bottomward some cylinders operating. Out of four, a computer affairs automatically cuts bottomward to 2 cylinders advisedly to cut on ammunition consumption, ” He added the aforementioned applies to the GDi engines on Pajeros.
At that speed, it has what is alleged a angular approach which compresses on the burning to about bisected of what is declared to be consumed.
Common rail
Common abuse as a technology cuts beyond brands. Kasujja says accepting it on a agent depends on what the architect intends to accomplish because one can accept accepted abuse and say MiVEC for a agent agent but not in petrol.
Aloysious Kawooya, the Quicklane administrator at Cooper Motors Corporation says the action of the Accepted abuse is to advance a assertive akin of burden of ammunition in the engine.
Kasujja explains that it has a burden sensor that detects whether the burden is accustomed or abnormal. If it is abnormal, it will address to the computer that the burden has alone and will accelerate a arresting to the dashboard to active you that you got a botheration about with the ammunition system. Its aim is to abbreviate ammunition burning and abate on emission.
CGi (Charge Gasoline Injection) technology is acclimated by Mercedes to abate ammunition burning and carbon discharge but with the adeptness to aftermath aerial adeptness as well.
Kasujja mentions that the assumption of operation of all engines are the aforementioned irrespective of car brand, type, admeasurement or ammunition blazon but the differences is the technologies brands out in their cars that accomplish slight differences.
“About bodies acceptable fanatics of accurate systems say VVTi, they accede factors like ammunition consumption, accessible additional parts, one that technicians know, types of engines are far from their knowledge. And the resale amount too is important. Alike if the agent is activity to afflict them all the time,” he notes.
Ford uses DuraTorq TDCi (Turbo Agent Accepted abuse injection) arrangement in their engines that Aloysious Kawooya, says is additionally alleged High-speed engines. He says Ford cartage accept had that technology aback 2011 claiming added car manufacturers started in 2015.
He says they are alleged High-speed engines because a agent needs a abate agent to move a bigger anatomy but with a lot of adeptness clashing in the accomplished aback big cartage bare big engines. Actuality you charge a baby engine, adeptness it with a acceptable turbo, agent intercooler and alike the accession of the intercooler matters.
He explains that the arrangement uses bankrupt gasses advancing from the agent that are declared to escape through the exhausts. The Turbo takes it back, mixes it at aerial pressure, pushes it through the intercooler which is declared to air-conditioned the air because it is hot. The Turbo and intercooler assignment calm and can’t accept one after the other.
The turbo is declared to accomplish that air at a aerial acceleration so that goes into the agitation chamber.
On benefits, Kawooya says it gives abundant adeptness and beneath ammunition burning because it uses added of air and beneath of ammunition but has the aforementioned power.
The Duratorq TDCi agent technology is begin on a Mazda BT50 and a Ford Ranger.
D-4D (Direct Bang 4 Cylinder Accepted Abuse Agent Engine). Agent is injected as vapour into the agent at aerial burden application the accepted rail. The allowances are lower emissions and bigger ammunition efficiency. It is begin in the Toyota Hilux.
Nissan uses the CVTCS (Continuous Valve Timing Ascendancy System) agent technology. It is acclimated by Nissan to abate emissions and ammunition burning and discharge achievement while convalescent on agent performance.
CVT (Continuous Variable Transmission) is rather accepted for seamless automated accessory transmission. It is begin on the new models of the Toyota RAV4
The basal band is, car agent technologies are added agnate than they are different. They accept accepted objectives of acid on emissions to save the environment, advance ammunition adeptness while convalescent agent performance.
