The Turbo Story

A turbocharger is a clever device that allows an engine to produce more power. A non-turbocharged engine uses regular uncompressed air and fuel. This works fine, but if you compress air, that is take air that normally fills, say, a pint glass and squish it down to a half-pint glass, then inject it into the cylinder, you’ll get a bigger bang because there’s more oxygen for the fuel to mix with. A bigger bang makes the cylinder move faster which makes the crankshaft turn faster which means a bigger smile on your face!

I remember in the 80's everything was given the Turbo moniker, razors, pens, computers. I had the Saab 99 Turbo and I remember my girlfriend of the time telling her friend "Andrew has just bought the Saab 99 Turbo, it's amazing" and then turning to me and asking "what is a turbo?" My ratio of girlfriends was the highest it has ever been when I owned that car despite the backseat being very uncomfortable, not as uncomfortable as the RX7 MKI though

My favorite thing about the 80s turbo craze was all the totally non car related products that were suddenly labeled turbo. Turbo hair dryers, turbo windsurfing boards, turbo socks, and so on. apparently anything could be turbo! In Sweden, the suddenly common microwave ovens got the nickname "bun turbo", for obvious reasons.

I was a teenager when my Dad bought a 1979 Saab 99 Turbo. Tons of Turbo lag. Lots of excitement building up that turbo whine! We've probably had 30 Saabs from the 1960's through our last on - a 2005 9-3. That 1979 99 Turbo was probably my favorite! It was just so darn iconic.

The turbine on the exhaust is not 'free' - the restriction it places on the exhaust manifold reduces the power produced by the engine just as a mechanical blower takes up some power.

@paulhorton5612 4 жыл бұрын

Exactly - manifold back pressure takes away some power. And turbocharged engines must run at lower compression ratios further reducing the energy available to extract from a given charge. There are trade-offs everywhere. The big gain is in volumetric efficiency (more output from a given displacement).

@fastinradfordable 3 жыл бұрын

And.... it MORE than makes up for the energy consumed. My vnt turbo begs to differ about “taking away power” And even when not making boost, It more than makes up for restriction by reducing pumping losses.

@ItsFriscoBaby 3 жыл бұрын

On a compound turbo setup the big turbo doesn't take over once it has spooled up. The small turbo feeds the engine all the time, it is just fed with compressed air once the larger turbo is spooled.

Another in a great series of videos. Thanks for bringing up “turbos” for aviation. In fact, in the 1940s most manufacturers called these “turbosuperchargers” and the main manufacturer was General Electric, as they had experience with high-speed turbines due to making them for power generation. As a result, GE was one of the first US companies to develop jet turbines, due to their experience with turbos during WWII.

Hi - great video as usual. But I think the most the Esprit with the 2.2 litre turbo ever produced was 300BHP (in the Sport 300). The 500BHP (limited to 350BHP) you mention is for the twin turbo-charged 3.5litre V8.

The Lotus Esprit was generally sold with a 2.2L turbo engine in the 1990s, though 2.0L turbos were sold (mainly in the Italian market). However, none of them were producing 500hp; that was unique to the 3.5L twin turbo V8s from 1996 onwards.

While turbochargers has made smaller engines more powerful, its stress on lubricants has resulted in a number of engine reliability issues with recent engines. That's why the American Petroleum Institute (API) introduced in May 2020 the _AP_ motor oil certification standard, one designed for the high-stress environment of modern turbocharged engines.

Minor point: the compression is always done by a (you've guessed it) compressor. The compressor is either powered by a turbine that in turn is powered by the exhaust, or gets its power straight from the crankshaft. The former is then called turbocharging, the latter supercharging.

@chengong388 4 жыл бұрын

Pretty sure turbo chargers aren’t free, the back pressure leeches power off of the engine just like a supercharger.

@heikopanzlaff3789 4 жыл бұрын

depends from a little bit to hardly any according to the engine design. Superchargers drain a lot of power so in most cases it is better for the customer to have a bigger displacement than a supercharger. They are also more complicated and costly than turbochargers.

Isn't the extra air/oxygen useful because you can inject more fuel with the same air/fuel mix proportion?, not just 'because there’s more oxygen for the fuel to mix with'. Perhaps that's what was meant, but it's not very clear - it makes it sound like it's just burning better because of the extra oxygen.

And you may be surprised to hear that the MG Metro Turbo used the same turbine as the Lotus Esprit. The reason is that for the metro, with a smaller engine, would actually be more likely to spend more time at part-throttle, so part-throttle fuel economy was considered more important than outright power at max throttle. That was their thinking apparently but I'm not quite sure how the physics of that works out.

I would guess that there are more turbo-equipped vehicles in Europe than the US for two main reasons. Firstly, the American's love of large capacity engines that gulp cheap fuel, as opposed to the European need for power _and_ fuel efficiency. And, secondly, because of the popularity of diesel engines in Europe. Diesels being especially crappy until the turbo spools up. I can certainly attest to the number of life-before-my-eyes moments my diesel Passat has given me as it rolls limply across an intersection in front of some barely subsonic juggernaut, before suddenly lighting up the front tyres and attracting unwanted attention from Mr. Plod.

I think what you’re trying to say is that if you compress the air you can get more air in to the cylinder. Same volume but more mass = more oxygen so more fuel can be added. Also, turbo lag is the delay in engine response AFTER you put your foot down on the accelerator, not BEFORE you put your foot down lol
