How Does The EGR And Secondary Air Injection Work With The Catalytic Converter?
The perfect internal combustion vehicle would be able to put the exact amount of fuel and air into the combustion chamber. If the perfect combustion event happened, you would get nothing more than water and carbon dioxide. There would not be any unburned fuel or oxygen. What would be needed to make this happen? Direct injection into the combustion chamber is a good start. You would also need the perfect combustion chamber free from hot spots – areas of unwanted turbulence or carbon build up. In the mean time, we have exhaust gas recirculation systems (EGR), secondary air injection and catalytic converters to reduce emissions
Nissan VQ35-Series Water Pump: Chain-Driven Water Pump Replacement
At the top of the list for the most difficult water pumps to replace is the Nissan VQ-Series V6 engines. The pump is turned by the timing chain and is nestled in the engine block. This can make for a very difficult job no matter if the engine is mounted transversely or longitudinally. The VQ35-series of engines can be found in 2001-current Nissans and Infinitis. Book time on this job can range from 2- to 3.0-hours depending on the model and layout. There are no shortcuts.
The Gates Corporation And ASE Name Ronnie Bush, Sr. Instructor Of The Year
The Automotive Aftermarket division of The Gates Corporation announced in collaboration with the National Institute for Automotive Service Excellence (ASE) that Ronnie Bush, Sr. is the Gates Tools for Schools/ASE Instructor of the Year.
Dayco Adds License Plate Parts Lookup, 3D Training To Patent-Pending App
Dayco Products, LLC will release a major update to its industry-first VIN-scanning app during the Automotive Aftermarket Products Expo (AAPEX) in Las Vegas. The new update, available in both the App Store and Google Play Store, includes first-of-its-kind license plate parts lookup technology as well as Augmented Reality training features, said the company.
Winter Starting And Charging System Maintenance
In addition to checking the strength of the antifreeze, a cold-weather starting inspection should also include testing and visually inspecting the battery and cables, starter, alternator and changing to the auto manufacturer’s recommended engine oil. Because cold weather slows down the chemical reaction between its electrolyte and its battery plates, the average battery can lose more than 50% of its cranking amperage at 0 degree F. For that reason, cold-weather starting quickly separates OE-specification from non-OE-specification batteries.
Gates Announces Release Of New Products To Serve Automotive Aftermarket
The Gates Corp. recently added 394 new parts to its catalog of quality automotive products. The new parts include turbocharger hose for VW and Audi applications, branched radiator hose, timing component kits with water pump, and small I.D. and molded hose.
Diagnostic Dilemmas: Solving Starter And Alternator Problems
The starter “solenoid” is actually a combination of an electric relay and solenoid. The relay portion electrically connects the starter armature to the battery. The solenoid portion mechanically engages the starter’s drive pinion with the engine’s flywheel gear.
Component Connection: The Mod Squad – Boosting Engine Power With Turbochargers And Superchargers
The power that a naturally aspirated engine can make is limited by its displacement and how efficiently you can make it breathe with cylinder head, camshaft and induction system modifications. The engine can only inhale so much air because the atmospheric force that’s pushing air into the engine is only 14.7 lbs. per square inch at sea level. To make matters worse, atmospheric pressure decreases with elevation. Air density also decreases with temperature because hot air is thinner than cold air.
Diagnostic Dilemmas: Changes In Our Diagnostic Outlook
Everybody likes to read about a Diagnostic Dilemma that has been solved to everybody’s satisfaction. But this month I have an unsolved Diagnostic Dilemma that is more about customers than cars. This particular dilemma involves a 2005 Ford Crown Victoria with headlamps that randomly lose power during night driving.
Tech Feature: Hall Effect Sensor Diagnostics
Hall effect crankshaft position (CKP) and camshaft position (CMP) sensors are critical components of an engine management system. The inputs they provide enable the powertrain control module (PCM) to determine engine speed and position including where a given cylinder is within the four-stroke cycle.
