Safran unveils new engine prototype

Airliner makers could soon see a more fuel-efficient engine in the sky, thanks to Safran’s new open-rotor engine prototype. The new architecture could reduce fuel consumption by 15 percent. The new engine is expected to be ready for testing around 2025. Ultimately, it may even affect airline fares, since it would cut the cost of fuel. But there are a few hurdles to overcome before this new engine can reach the skies.

The new prototype uses additive manufacturing, dual-channel fadec, and unspecified new materials to produce an engine with 1,100 horsepower. The engine’s power-to-weight ratio will be up to 30 percent higher than the current engine, making it more efficient in offshore missions, search-and-rescue, and firefighting missions. Safran named the new engine prototype after a geographical feature in the Pyrenees mountains. The name of the high-altitude lake is Arrius. Another name is Makila, which refers to a traditional Basque walking stick. The new engine prototype will also be used in military transport helicopters.

Scuderi Group unveils split-cycle engine

The Scuderi Group has revealed a prototype of its split-cycle engine. The prototype can store compressed air to push the power cylinders down when the engine is at a low power level. This is an important feature to consider, as proper use of compressed air can increase fuel efficiency by 50 percent. …

5 Essential Car Engine Parts and Functions

- by Anthony McCarthy

A car’s engine is composed of around 200 parts. Knowing how each of them works is essential for maintaining your car’s longevity. Here are 5 essential parts of your car’s engine that you should know. Understanding how these parts work will help you know what’s wrong with your car, and can help you find a reputable mechanic who can repair it properly. Also, keep in mind that not all of these parts are the same.

Oil pan

The oil pan in a car engine is an integral part of the vehicle’s engine. It holds six liters of oil and is designed to fit snugly into the vehicle’s available space near the chassis and steering gear. The oil pan is also designed with ribs to reduce turbulence and improve stiffness of the flat section. In addition, it features warm-embossed brass inserts to accommodate the oil level switch and discharge screw.

Piston

Piston car engine parts and functions are crucial to the proper functioning of an automobile. Pistons play an integral role in the combustion process and generate energy for the rest of the engine parts, including the crankshaft and flywheel, which transfer this energy to the wheels. Pistons also feature valve reliefs to reduce the amount of pressure on the crown, which is the area directly in contact with hot combustion gases. Pistons also have a slight inward taper from the bottom, allowing for greater clearance around the top land.

Intake manifold

The intake manifold is an integral part of your car’s engine. It is responsible for providing the air-fuel mixture that powers your engine. During the combustion process, air is sucked into the manifold through the throttle body. Fuel is injected into the manifold’s other end via the fuel injector. When the mixture reaches the cylinders, it is burned by …

New Rotary Engine Design

- by Anthony McCarthy

The new rotary engine is a welcome development after years of meh emissions and unstable durability. However, a new startup firm, Astron, has developed a 33-pound rotary engine that produces 162 horsepower. This is a far cry from the typical 840- pound turbocharged V8 diesel engine with 340hp and a power-to-weight ratio of 0.40hp/lb.

Szorenyi rotary engine design

The Szorenyi rotary engine is a simple, purely mechanical engine with one chamber, a rotor. It uses a mathematically defined stator. In the Szorenyi rotary engine, the rotor segments change from a square configuration to a rhombic one during rotation. This design achieves a volumetric efficiency of 100%. It can operate with a wide-open throttle without knocking. Its main features are centered around the combustion chamber and the pressure on the stator. Its internal structure features a direct contact power take-off crank mechanism.

REDA’s new engine design can also run on diesel fuel, with a pre-compression phase. Its design is aligned with the concept of the “one fuel” by the U.S. military. It is described in a SAE Technical Paper. The Szorenyi rotary engine is capable of running on gasoline, avgas, butane, hydrogen, and propane. Its well-separated inlet and exhaust ports allow for a variety of fuel types, including ethanol and biodiesel.

Mazda’s new rotary engine design

It is unclear whether Mazda will continue to produce the iconic rotary engine, which was last seen in the MX-5 in the late 1980s. While the company has stated that it will return with the MX-30 in 2022, rumors have swirled that the rotary is being shelved for the time being. In an effort to keep the engine relevant, Mazda is looking at several auto applications. The new engine will also be used as a range extender for electric vehicles.

How to Increase the Efficiency of a Petrol Engine

- by Anthony McCarthy

The efficiency of a petrol engine is determined by its total power output, which is proportional to its pumping loss. Generally, pumps require 20% of the engine’s total power production to produce rated power. However, the pumping losses are minimal at low speeds. The pumping loss increases with speed. Hence, engines should not be driven below their rated power. The following are some of the factors that contribute to the efficiency of a petrol engine.

Fuel-lean running

When your engine is running lean, you are making it work harder than it should. This results in a reduced power output, difficult starting and increased gas consumption. Left unchecked, this problem can cause irreparable damage to your engine. A fuel- lean problem can also be the cause of your car’s Check Engine Light. Below are a few common symptoms of a fuel-lean condition.

A faulty fuel pump, a clogged fuel filter, or an unbalanced air-fuel mixture are all common causes of lean-running engines. Sometimes, a faulty sensor may send the wrong information to the ECU. In both cases, fuel can become diluted and not burn properly. However, the resulting engine is not as dangerous as it seems. Even if the engine runs lean, it is still best to use a full tank of petrol.

Magnetization of petrol fuel

The use of a magnet for the atomization and burning of petrol fuel is a novel approach to increase the efficiency of the petrol engine. In addition, it saves oil, which is an important consideration when reducing the overall fuel consumption. A practical test of the utility model showed a 30% reduction in fuel consumption and oil emissions while reducing smoke emissions. This method is also simple to install and modify.

The Difference Between Power and Torque in Cars

- by Anthony McCarthy

If you are comparing the differences between horsepower and torque in a car, you will notice that the former has more pulling power. Generally speaking, torque is important for trucks, as they need that muscle to haul heavy loads. But smaller cars have plenty of torque, too. The 2021 Chevrolet Camero SS has 455 pounds-feet of torque and is capable of accelerating from zero to 60 mph in four seconds.

Fuel efficiency

When a vehicle accelerates, it uses torque. Power, on the other hand, comes from horsepower. Torque helps a car start and maintain speed, while horsepower allows it to accelerate quickly and smoothly. High horsepower cars are designed for those who want speed, but they also require more fuel than low-power vehicles. If you’re in the market for a new car, make sure to compare the horsepower and torque ratings.

Usually, high-power engines don’t produce a lot of torque. Torque is generated at higher engine speeds, so that the amount of torque is usable at a narrower range of speeds. This narrow power band limits the car’s range of usability, which makes it unsuitable for towing or relaxing driving. In addition, it can be difficult to make decisions based on power alone.

Performance

Torque and power are two output parameters that determine the quality of the vehicle’s performance. Torque is measured by the rotation of the crankshaft while power is the rate at which the vehicle can do the same work. They also have a direct relationship, as the latter can help the vehicle move at a fast pace or up a steep hill. However, you may have questions about these terms. To answer these, learn more about the performance difference between power and torque in cars.

Torque has many benefits compared to horsepower. Higher torque enables a car …
