[dropcap]I[/dropcap]f you had to ask a question to some truck enthusiast and let’s say that you wanted to know what the engines pickup lines were, the odds of mentoring the power stroke are definitely great. Ford fans may also tell you that one of the biggest motors has been so far put within Fords. Yes, a lot of people will say that around 7.3 have not been in production for more than 15 years now. And in spite of that, it is quite tough to forget the kind of impact the truck scenes have made in America. So we have decided to put together a quick history of power stroke engines and what we can expect from them in the coming days.
An understanding of power stroke engines
First of all, there are approximately 4 stroke engines (suction stroke, power stroke, compression stroke as well as exhaust stroke)
Within the suction strokes, the suction is created within the engine cylinder as the piston keeps moving downwards. The suction will pull the air as well as the fuel mixture inside the cylinder.
When it comes to the compression stroke, the piston which is present will move upwards on the dead center. Just like the piston keeps moving upwards, it will compress the air-fuel mixture as well as the compression results within an increase the pressure and temperature right inside the cylinder. Just like that, the air-fuel mixture will heat up like the piston reaches towards the top center and is ignited by introducing sparks with the help of a plug.
Within the power stroke, the mixture of air and fuel will ignore and there will be combustions because of the spark that results in a further explosion. This also applies as a very effective pressure of the piston pushes it downwards. The explosion will also apply effective pressure on the piston and it will reach towards the dead center, down at the bottom. After this, the crank will transmit the torque towards the clutch.
Finally, the exhaust stroke, the whole gases of expansions will be released towards the outside in order to get a nice change for the mixture of air and fuel. Therefore, the piston will move towards the dead center and towards the top center. As the piston reaches the TDC, the valve will open and the gas will be removed from the system.

What was present before the power stroke engine?
The power stroke engine goes back before in time in the year 1982 when General Motors had started to offer the economical 6.2 litres Detroit diesel in all of their pickups. Right after that, Ford had realized that the potential for these diesel trucks within the market. But, instead of just looking for efficiency, Ford went ahead and decided to utilize the engines of the diesel and its other strengths. As a result of that, within just a year, once the Detroit diesel went right into the service, Ford started to sell many heavy-duty pickups. Produced by none other than International Harvester, the IDI began to develop a name for itself with the help of an indirect fuel injection system. Even though it was aspirated very naturally, the 6.9 litre IDI got hold of a respectable 170 hp between 315-340 pounds.
When the year 1988 came into the scene, the IDI was boosted by around 7.3 liters. The power and torque were also boosted like it was a naturally aspirated engine. Even in spite of that, the IDI was considered highly popular by many truck buyers. In the year 1993, IDI also got hold of a turbocharger which gave it around 190 horsepower and more than 380 pounds of torque.
Engine Basics
The power stroke first generation was a great combination of one simple, overhead and two valve designs that were coupled with some great power ratings along with a diesel engine that is effective and reliable. It should be able to last for about 300,000 miles and more than that. The engine has been used as a bore of about 4.11 inches and comes with a stroke as close to 4.18 inches. It also has a cast-iron block, some cylinder heads as well as forged steel connecting rods. The ratio of the power stroke has been lowered than the predecessor at the rate of 17.51. The dry weight of the engine is about 1000 pounds in total.
The second generation power stroke
The power stroke from the second generation started at 7.3L within year 88. This version was given inter cooling and it was fitting for all the trucks labeled as ‘Super Duty’ and was put for more torque as well as horsepower. The first year Super Duty along with 00s engines put close to 235 hp along with 500 pounds of torque. Apart from that, the 99 and the 00 models also shared the engines. It was spotted by the powerstroke badges that were visible right in front of the fender wells of the truck. The badges were built in the year 2000 and then later were displayed right on the door panel’s bottoms.
The future of power stroke
Now that we have seen the global attitudes towards all the diesel emissions as well as the consumption of fuel, it can be a little difficult to see the next power stroke any time near. However, we are quite sure that the big diesel over there doesn’t really require any torque or power. However, that also does not mean that there will not be any room for some progress in the design of trucks. We have recently learned that this Ford F-150 will end up receiving a diesel engine, which will battle all the upcoming fancy cars in the future. As of now, you can expect 250 hp or maybe 450 pounds of torque within a package that will get approximately 30 US MPG right on the highway itself.
