Project Integra

The Acura Integra is a highly customizable, highly modifiable Japanese import within the US market. This will become the official project car of Engineering Explained! Let's have some fun, modify the car, and learn! Any and all suggestions are welcome, if you can contribute to the project in any way, please reach out! I will begin by testing out the parts I already have. I'd like to work on the engine (rebuild, swap, turbo, cams, intake, exhaust, etc.), suspension (coilovers already installed, camber kit, bushings), wheels, brakes, tires, weight reduction (body panels, hood, steering wheel, seats, battery), clutch/transmission (flywheel, already have an aftermarket clutch), chassis reinforcement (roll cage, strut tower brace, etc.), interior/exterior enhancements.

2014 Formula 1 Engine + ERS

2014 Formula One engines. In 2014 F1 cars will be powered by 1.6L V6 turbocharged engines revving up to 15,000 RPM. The new F1 engines will also incorporate ERS, or energy recovery systems. The technology is ever improving for more advanced vehicles that operate at increased efficiencies. ERS is made up of multiple systems. MGU-H, MGU-K, and Energy storage will all play a critical role in increasing the efficiency of the vehicles, and adding an additional 160 HP for 33 seconds per lap on the track.

How to Replace A Rear Trailing Arm Bushing

How to replace the rear trailing arm bushing in a 1994-2001 Acura Integra, 1988-2000 Honda Civic, 1988-1991 Honda CRX, and 1992-1997 Honda Del Sol. The rear trailing arm bushings isolate and reduce road shock and vibration, and help absorb axial and radial movement of the suspension. The bushing can crack and harden over time, as well as break, and will eventually need to be replaced.

The following video shows replacement of the trailing arm bushing in a 1999 Acura Integra GS. This procedure will be nearly the same for all models listed above.


The two necessary items to replace the bushing as shown in the video are trailing arm bushings, and a Schley tools bushing extractor. Though the bushing extractor is fairly prices, I've heard of shops charging as much as $800 for the bushing install, making it well worth the price in my opinion. The tool worked great, my only concern is with the bushings themselves. Make sure to measure the bushings when they arrive, and check the outer diameter. If the diameter is greater than 3.17" I wouldn't even attempt to install them, return them and order another set.

Electric Cars

How do electric cars work? Starting from the ground up, electric motors are the basis for electric cars. What is an electric motor? How does an electric motor work? This video will explain the fundamentals of electric motors, including an overview of the "left hand motor rule" which is the basic principle that explains how motors work. Using a magnet and a flowing current through a wire, an electric motor can be created.


Okay, so we have the basics, but now electric motors don't quite make sense. Magnets are the basis for electric motors, so we'll need to understand them next. Fundamentally, magnets can be explained through quantum mechanics. This video will explain it in a bit easier fashion. Magnets basically boil down to the magnetic fields produced by electrons, due to the electrons spin. An electron's spin is an intrinsic property. When electrons of equal spin line up, they form larger magnets. In some rare earth metals, this can occur naturally. Most minerals and molecules have paired electrons with opposite spin, so the magnetic fields cancel out. Magnets are the driving factor of how motors work.


So now lets talk about how you can create a magnetic field without a permanent magnet, and by using a current instead. Electromagnets use an electrical current in order to produce magnetic poles. The operate just like permanent magnets, however they require the presence of a flowing current. By passing a current through a wound coil of wire, north and south magnetic poles will form.


Now that we have a better understanding of electric motors, let's take a more detailed look at how they operate. 3 Coil DC motors will be explained in this video. Direct current motors use a direct current, passing through wire coils wrapped around armatures on a motor rotor to produce magnetic fields (electromagnets). These electromagnets are surrounded by permanent magnets, which cause the rotor to rotate when a current pass through it.


Finally, we can begin to understand electric cars. Electric cars use electric motors to power the vehicle, rather than an internal combustion engine. The result is a vehicle that produces no emissions, requires little maintenance, and is extremely cheap to recharge. With advances in lithium ion batteries, electric cars are becoming more and more popular.


Hopefully this provides a good basis for understanding electric cars. Feel free to subscribe to my YouTube channel for upcoming videos relating to electric vehicles, and other automotive topics.

What is a clutch disc? What is a clutch? How do clutch discs work? What are the different parts of a clutch disc? This video features a 6 puck Yonaka Motorsports performance clutch for B-series Honda motors. A clutch disc is made up of a main plate, to which friction material is connected. The main plate is also connected to two retaining plates, which surround the clutch hub. The retaining plates are held together with stop pins, and when the retaining plates move they press on the springs inside the hub. The springs are used to cushion the clutch engagement, and this is dampened out by the friction disc sandwiched between the two retaining plates.

What is a performance clutch?

What is a performance clutch? What is a clutch kit? How does a performance clutch work? A performance clutch basically involves three changes over traditional organic clutches. This video features a Yonaka performance clutch kit. A performance clutch has a higher clamping force on the pressure plate (via the diaphragm spring). Performance clutches use different materials which can absorb less heat and that don't lose performance at higher temperatures. Finally, performance clutches use a "puck" design, 3 puck, 4 puck, 6 puck, which increase the pressure on the friction material, to prevent slip.
