New Engine Prototype and Split-Cycle Power Plant From Scuderi Group

- by Anthony McCarthy

This week’s headlines include a new engine prototype from Safran, a split-cycle power plant from the Scuderi Group, and Michigan State revealing a 25-kilowatt version of its own experimental system. And despite the waning production of Ford GTs, there are still a few developments worth checking out. Here’s a closer look at some of the major developments. Also: The price of a one-off direct-injection system has reached the stratosphere, and Doyle is looking for investors.

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 …

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.

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 …

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 …

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. …
