LIQUID COOLED VS AIR COOLED ENGINE REVIEW by sunil joseph

CLICK THIS TO REGISTER AD EARN ONLINE JOBS

                                                           

Friends we are familiar with the two words oil/liquid cooled engine and Air cooled engine.But those people who are new to riding their own bike may find it difficult to distinguish between these two types of engines.That's why i'm opting to share a small review about these two types of engines and their merits and demerits.http://adf.ly/4213010/liquid02

OIL COOLED ENGINE OF HYONSUNG

As engine generates mechanical power and waste heat energy at the same time, they need cooling to prevent them from over heating and break down. There are two types of engines  air cooled and liquid cooled engines. Liquid cooled engines use a mixture of water and other chemicals like anti freeze and rust inhibitors.

While some other, liquid cooled engines do not use any water but special fluids with enhanced properties like ethylene glycol. On the contrary, air cooled engines use air but no water or other chemicals to cool themselves. Liquid cooled and air-cooled engines are interdependent as most liquid cooled engines use some amount of air to cool over heating and air-cooled engines use liquids for cooling down.http://adf.ly/4213010/engine0046341(click this link to watch the engine inner part)

MERITS AND FEATURES OF LIQUID/OIL COOLED AND AIR COOLED ENGINE

• A motorbike with liquid cooled engines is smoother and more resistant to breakdown than air-cooled.
• A liquid cooled engine produces more power/torque than an air-cooled one.
• A liquid cooled engine, since cooled by liquids, maintains a better control temperature.
• Air-cooled engines are fuel efficient, affordable and require lesser engine space than that of liquid cooled engines.
• The Maintenance costs of liquid cooled ones are higher than air-cooled engines.
• Liquid cooled ones are easy to operate (better riding experience) but certainty of liquid spilling out is high.
• Air-cooled engines are nosier and somewhat harsh than liquid cooled engines.

VERDICT

AIR COOLED ENGINE

Although liquid cooled engines are quite good as regards cooling, power and efficiency people prefer air-cooled engines because of their cost efficiency, fuel efficiency and low cost of maintenance. However, if you wish to avail more powerful and torque then opting for liquid cooled engines are a good deal. In simple words, go for oil cooled engine if you need more power and if you need is for getting more fuel efficiency then go for Air cooled engine.It is upon your choice to select which type of engine you want.

DIGITAL TWIN SPARK IGNITION (DTSI) REVIEW by sunil joseph

Get paid to share your links!

                                                             Guys, we are familiar with the word DTSI.But most of us don't know about what it means.The Indian bike manufacturer Bajaj has succesfully launched PULSAR series bikes which changed the bike concept in the roads.http://adf.ly/4213010/dtsiengine02The digital twin spark technology(DTSI) was famous in the bike concept.This review is shared to you to know about this engine and to know about various aspects of this engine.So read carefully to know the techniques adopted in the working procedue of DTSI engine.

PULSAR 180 DTSI ENGINE

It is very interesting to know about complete combustion in automobile engineering, because in actual practice, perfect combustion is not at all possible due to various losses in the combustion chamber as well as design of the internal combustion engine. Moreover the process of burning of the fuel is also not instantaneous. However an alternate solution to it is by making the combustion of fuel as fast as possible. This can be done by using two spark plugs which spark alternatively at a certain time interval so as increase the diameter of the flame & burn the fuel instantaneously. This system is called DTSI (Digital Spark Ignition system). In this system, due to twin sparks, combustion will be complete.

This innovative solution, also entailing a special configuration of the

hemispherical combustion chambers and piston heads, ensures a fast,

wide flame front when the air-fuel mixture is ignited, and therefore less

ignition advance, enabling, moreover, relatively lean mixtures to be

used. This technology provides a combination of the light weight and

twice the power offered by two-stroke engines with a significant power

boost, i.e. a considerable "power-to-weight ratio" compared to quite a

few four-stroke engines.

http://adf.ly/4213010/dtsiengine-03This power unit, equipping the naturally aspirated 2-litre used on the Alfa 164, is a direct dilative of the engine fitted on the 2.0 Twin Spark version of the Alfa 75, a recent addition to the Alfa car range. It includes a number of exclusive engineering solutions resulting in superior power output and exceptional peak torque for this cylinder capacity. Its main characteristics are:

Digital electronic ignition with two plugs per cyl

inder and two ignition distributors

Twin overhead cams with camshaft timing variation

 Injection fuel feed with integrated electronic twin spark ignition

Cylinder capacity amounts to 1,962 cc thanks to an 84 mm bore and 88.5 mm stroke with the Compression ratio 10: 1.Maximum power output at 5,800 rpm is a remarkable 148 BHP DIN, while maximum torque, of 19 mkg DIN, is reached at 4,000 rpm. The shape of the torque curve has been perfected to make available fully 16 mkg when revving speed reaches 2,000 rpm and 18 mkg as early as 3,000 rpm, thus making the engine's performance much more responsive.

ENGINE MADE

DTSI ENGINE PICTURE

The engine used on the Alfa 164 T. Spark is a four-in-line cylinder unit whose weight has been considerably reduced with all aluminium-alloy engine block, cylinder head, oil sump and tappet covers.

Eight counterweights ensure optimal balancing of the high strength nitride steel crankshaft.

The pressed-in cast iron cylinder liners feature wet mounting for more effective heat dissipation.

FUEL EFFICIENCY

The Alfa 164 T. Spark power plant is equipped with the ML 4.1 Bosch Motronic multi-point injection system, controlled by the same microprocessor which governs the twin spark ignition and variable valve timing Systems.

The excellent volumetric efficiency of the Twin Spark engine is also enhanced by the special straight section individual intake man folding that cuts down losses and fully exploits intake resonance for better mid-range torque.

Having all thermodynamic cycle components under the wings of a single electronic control unit means that the power plant used on the Alfa 1 64 T. Spark can guarantee-in addition to outstanding torque and power figures-regular, smooth running at all speeds regardless of

load. Moreover, this engine features particularly attractive specific fuel economy compared with rival naturally aspirated units in the same displacement class.

WORKING

http://adf.ly/4213010/dtsi-engine-pic-01The working of DTS-i engine is very similar to 4-stroke engine but here the only modification done is we are using two spark plug at two ends of the combustion chamber. Which require less time to reach the farthest position of the combustion chamber and optimize the combustion chamber characteristics.

IGNITION

COMBUSTION PROCESS

The ignition system on the Twin spark is a digital system with static spark advance and no moving parts subject to wear. It is mapped by the integrated digital electronic control box which also handles fuel injection and valve timing. It features two plugs per cylinder.

This innovative solution, also entailing a special configuration of the hemispherical combustion chambers and piston heads, ensures a fast, wide flame front when the air-fuel mixture is ignited, and therefore less ignition advance, enabling, moreover, relatively lean mixtures to be used.

ADVANTAGES OF USING DTSI ENGINE

Less vibrations and noise

Long life of the engine parts such as piston rings and valve stem.

Decrease in the specific fuel consumption

No over heating

 Increase the Thermal Efficiency of the Engine & even bear high loads on it.

Better starting of engine even in winter season & cold climatic conditions or at very low temperatures because of increased Compression ratio.

Because of twin Sparks the diameter of the flame increases rapidly that would result in instantaneous burning of fuels. Thus force exerted on the piston would increase leading to better work output.

DISADVANTAGES OF USING DTSI ENGINE

There is high NOx emission

 If one spark plug get damaged then we have to replace both

The cost is relatively more

You spend double the amount on spark plugs when it is time to replace them.

The engine tends to overheat and loose power at higher speeds as compared to a single plug engine.

 In case the Engine is kept unused for a long time soiling of spark plugs occur. Twin Spark system helps to reduce this problem.

VERDICT

Hence it can be concluded that the application of these technologies in the present day automobiles will give the present generation what they want i.e. power bikes with fuel efficiency.http://adf.ly/4213010/engine-dtsi-valves Since these technologies also minimize the fuel consumption and harmful emission levels, they can also be considered as one of the solutions for increasing fuel costs and increasing effect of global warming.

PERFORMANCE

This bike is provided with a powerful 223cc 4-stroke engine with air cooled that provides 17bhp at 7000rpm.This bike has a 5speed gearbox with 1down and 4up pattern.This powerful engine is useful to maintain low speed in higher gears.As this bike comprises a sporty and commuter looks it can be used by any type of customers.The bike enables the rider to feel confident in higher speeds as this bike uses its 223cc engine.If this bike had wider rear tyres would be nice like FZ series as this is helpful while cornering.Eventhough this bike satisfies the needs of the customer.

HANDLING

The seating position is comfortable and enables the rider to ride relaxly and sporty.The step up seat gives it a new generation feeling and this feature enables comfort to the pillion also.the foot pegs are rubberised and this provides greater grip to the rider and the pillion.But it is difficult to the rider while kick starting the bike as the foot pegs are not in a good position.And every time he has to fold the foot peg inorder to kick start.

MILEAGE

The bike delivers a mileage of 30-35 kmpl in city and 40kmpl in highways as this is acceptable to this type of a powerful engine.

SUSPENSION

Karizma R uses telescopic fork at the front and use adjestable hydraulic shock absorber in the back.It will be better if this bike is provided with a monoshock absorber at the back as this gives a greater stability to the bike and greater comfort.

BRAKING

The bike has got a disc brake in front and a drum brake at the back.it woul be better if the Karizma R provides a rear disc brakes.Overall the rear drum brakes also performs well in this bike.

This bike is available in 5 variants.
