A smaller engine 1.0 lit petrol turbo can generate high torque of 178 nm torque (as in Kushaq) whereas some engines of 1.5 lit (Maruti s-cross) generate lower range 138 nm torque.
1.0-1.2 Litre Engines
You'll get a good fuel economy out of them, as the smaller capacity means less fuel is used. This is great if you mainly do a lot of stop/start driving, such as in a city where there are lots of traffic lights, or if you usually make short journeys.
1.0-litre engines
Engines of 1.0-litre or less typically feature three or four cylinders and many now use turbochargers for extra power. You'll find them in anything from tiny city cars like the Hyundai i10 to medium-sized family cars like the Ford Focus, producing up to around 125hp.
Because of its compact turbocharger and some of Honda's inventiveness, the 1.5 is the best little and fuel-efficient engine currently available. In addition to the stated 162–192 lb. -ft. Of torque, the engine's 174–205 horsepower output is also noteworthy.
Yes, a turbocharged engine is better than a normal engine in terms of performance and efficiency. A lower capacity turbo engine can produce the same amount of power as a higher capacity NA engine.
Cons of a turbocharged engine
Affordability: Cars with turbocharged engines are typically more expensive than vehicles with standard engines because may need to use premium gas in your car. Reliability: Turbocharged engines may not be as reliable as standard engines. Engines with more parts have more that can go wrong.
Does it require special maintenance or care of any kind? No. today's turbochargers are designed to last the lifespan of the vehicle. The truth is, boosted engines require the same amount of maintenance and care that a naturally aspirated engine does.
Pro: A turbocharged engine produces more power than a non-turbo engine. Thus, you can use a smaller engine to achieve more output. Con: Turbo engines cost more money. Pro: You get more efficiency with turbo engines, saving money in fuel costs.
Today's 1.5 turbo engine goes about the same as a three-litre atmo engine, back in the day before Dirty Harry needed a Zimmer frame to grease punks with that enormous six shooter.
“Generally speaking, turbocharging is a great idea. It's a smaller engine, but you're still getting a decent amount of power,” says Mike Quincy, autos editor at Consumer Reports. “The idea with a smaller engine, especially a four-cylinder, is that you're going to get decent fuel economy without giving up power.
COLOGNE, Germany, June 18, 2014 – Ford's new 140 PS 1.0-litre EcoBoost is the most powerful 1.0-litre volume production car engine ever, delivering more power on a litre-for-litre basis than the engines powering the Bugatti Veyron or Ferrari 458 Speciale supercars.
Smaller engines, often ranging between 1-litre and 1.9-litre, tend to be the most economical as there is less fuel to burn to create power. However, this can often result in less power compared to a larger engine. They are usually more efficient if used for their purpose, which is most commonly city driving.
Are turbocharged engines more fuel-efficient than naturally aspirated engines? In theory, turbochargers can boost the efficiency of an internal combustion engine by anywhere from 10 to 30 percent.
One of the most significant advantages of a 4-cylinder engine is that it produces more power and torque than a 3-cylinder engine. This makes it a better choice for larger cars or those that require more performance.
I'd say a 1ltr petrol could be done around 180k km.
It would be mostly 100 kph and increasing to 110 when overtaking slower moving vehicles. High gear low revs and use coasting where you use very little petrol.
Compared to a naturally aspirated engine, there is significantly more pressure in the combustion chamber for a turbocharged engine. With enough of this pressure, the air-fuel mixture could ignite on its own without the help of a spark plug, causing knock, which could destroy the engine.
Changan Oshan X7 (185hp/300Nm) And the most powerful 1.5L turbo engine is there under the hood of the newly launched Changan Oshan X7 which generates 185 hp of power and a staggering 300Nm of torque, almost double of the 1.5L naturally aspirated engine in Honda City.
Go too small and spool-up time will improve but exhaust gases will revert back into the combustion chambers. Go too big and you'll find a bit more power, only a whole lot later than you'd probably like. The housing's radius also matters and directly affects turbine speed.
A turbocharger won't improve an engine's fuel economy, but it will get more horsepower out of a smaller, more fuel-efficient engine. When comparing turbocharger vs. supercharger, you're more likely to find a fuel efficient vehicle powered by a turbocharger than a supercharger.
A turbocharged engine turns into a fuel-hog under hard acceleration, because the large volume of air being pumped into the cylinders must be matched by a larger volume of fuel.
In short - a turbocharger is an extremely reliable component, it will normally last as long as your vehicles engines life. Manufacturers design turbochargers to exceed 300 000 km's in terms of service in a single lifecycle, however many turbochargers don't see this due to engine maintenance related issues.
Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it's possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.
The most common signals that you may have a blown turbo are: The car has noticeable power loss. The acceleration of the car seems slow and noisy. The car doesn't easily maintain high speeds.
