There's nothing quite like the scream of a two stroke engine and the smell of burning engine oil is always right there with that scream. In the world of motorsports its sound is unmistakable. Dirt bikes would see the two stroke engine utilized on early models because of the smaller size. Snowmobiles would also follow suit because of the light weight. It was only a matter of time before the ATV would make use of the technology to improve response, increase speed, and reduce weight. The first two stroke quad made it to market back in 1985. The Suzuki Motor Corporation would design and release the Quad Racer, a two stroke racing quad with a 246cc powerhouse. Although two stroke engines were appearing on earlier ATC's from the big four manufacturers (Honda, Kawasaki, Suzuki, and Yamaha), this quad in particular would set off a revolution of racing and sport riding. The ATV brought more stability to the table with four wheels versus the three wheeled ATC's. Engine size and power was utilized far better on quads when riders became more apt to keeping their wheels beneath them. The ATC was considered unstable and its production would eventually be outlawed, but the two stroke quad would flourish in the coming years with all the major manufacturers contributing their own version.

The two stroke engine was first invented back in 1878 but the first patented two stroke motor, a v-twin, didn't come along until 1904. The two stroke design has certain advantages and disadvantages when compared to a four stroke engine. One stroke equals one cycle, therefore a two stroke engine completes its energy production using half the cycles of a four stroker. This is because two stroke engines have no valves. The fuel intake, fuel ignition, and exhaust emission all happen on each cycle (or revolution) of the engine. Four strokes in comparison use a camshaft and a series of valves to separate all the phases of energy production. These additional components add overall weight to the four stroke engine. The two stroke however must burn oil during its ignition phase. This accounts for the blue or gray smoke which emulates from every two stroke exhaust port. Two stroke engines require oil to be injected simultaneously with the fuel or pre-mixed in the fuel tank. Two strokes also burn more fuel versus the four stroke powerplants. Citing emissions, noise pollution, and higher fuel usage, the two stroke engine has all but been eliminated from automotive and street motorcycle market, but the lightweight simplicity and sheer horsepower per cubic centimeter of these engines allowed them to flourish in the offroad market.

In their heyday, quad manufacturers flooded the market with their own two stroke engines. Beside the big four, Honda, Kawasaki, Suzuki, and Yamaha, other big players like Polaris as well as a variety of small scale Chinese manufacturers have capitalized on two stroke power for their quad ATVs. But new, lightweight, and more efficient four strokes would eventually become the accepted powerplant for the majority of production quads. The two stroke has been completely dropped from the lineup of most manufacturers in favor of reasonably quiet, fuel efficient, technologically advanced four strokes. Sport quad riding and organized racing have also, for the most part become four stroke events. As quickly as the two stroke engine entered the atv industry, it has, for the most part, fallen by the wayside even with new advances in emission technology, including reductions in odor as well as smoke.

What is an Auria TV?

Most people have never heard of Auria TV’s and that is not surprising. This type of HD TV is not well known, and you could even say barely known by most people around the world. What Auria is trying to do is position itself as a good alternative HDTV for people that cannot afford to buy the higher price high definition televisions.

And for the most part they do a pretty good job. Reviews of the Auria HD Televisions have been fairly good, surprisingly good for a TV that most of you have never heard of of. We will take a look at one of the better models of Auria TV’s, the AURIA EQ2288F 22″ LCD HDTV below.

Auria EQ2288F 22″ LCD HDTV

The Auria HDTV that is probably best known is the EQ2288F LCD model. This is a model that has received some pretty complimentary reviews by many people that have bought it so we will tell you a little bit more about it.

This is an LCD HDTV, not a plasma TV, so the contrast ratios are not going to be what a person would get from a quality plasma HDTV. But then again you are not going to be paying even close to the price you would pay for a high end plasma TV or even a high end LCD HDTV.

We have a link to more information below if you would like to read a more in depth review of the Auria EQ2288F LCD HDTV. But within this article we will give you some of the common positives and negatives that we have heard and seen from this TV.

The picture quality of the Auria EQ2288F 22″ LCD HDTV

One of the common praises of this TV is that the picture quality is really good, the quality actually seems to surprise many of the people that have purchased or tested this TV. They seem to think that because the TV is not expensive compared to other HDTV brands that the picture will not be very good.

We are not sure why anyone would buy a TV if they didn’t think the picture would be good, but apparently people do! But the picture quality is routinely praised by most people that buy this TV. It is not going to be as good as the top end HDTV’s but you probably know that already, but the picture is good.

Sound seems to be the major issue with some people

The one complain you here from a number of people that have bought this TV is that the sound can sound really cheap when they first get it. But usually those problems are resolved once you go into the audio tuning and make some adjustments. It seems at that point that most people think the audio is fine.

Should you buy the Auria TV?

It depends. If you have a budget that would allow you to buy a more expensive better HDTV then by all means you should probably look at the more expensive BETTER TV’s! But if you are looking for a good quality HDTV that doesn’t cost a lot the Auria TV’s are a good choice…and maybe a much better choice than you think.
