Another way to facilitate the access of the mixture to the spark was proposed by Japanese constructors. They introduced a groove in one of the electrodes. At NGK, this V-shaped groove is made on the face of the center electrode. Whereas in …

Spark plugs without side electrode
Czech constructors from the Brisk company assumed the assumption, that the ground electrode in a conventional spark plug limits the spread of the flame front, creating a "shadow zone". An original structure called Premium was created, which is characterized by the absence of a side electrode. …
Types of spark plugs
Combined semi-surface discharge candles. This type of candle differs from the standard plug with the insulator cone protruding from the body and the internal threshold at the bottom of the body.
During normal spark plug operation, the spark jumps from the center electrode to the side electrode by the shortest one …
Honda CBX 250 RS – Double rocker arms
The positive results of the use of four-valve engines in mass-produced cars have made, that Honda has used this in a single-cylinder motorcycle engine. This engine is fitted to the CBX 250 RS and has displacement 250 cm3 at the diameter of the piston 72 mm. Degree …
Audi Quattro 1984 – 80 – Sport
The 4X4 drive used in this car turned out to be the optimal solution, as it provides greater directional efficiency and an almost neutral cornering behavior, taking turns at high speeds, uniform wear of tires and less influence of driving forces on the system …
Turbocharged engine intake system
One of the more serious disadvantages of a turbocharged engine is its low dynamics in transitional states.
The possibility of a sudden increase in load here is limited by the inertia of the turbocharger rotor. The situation can be significantly improved by the use of a simple compressor bypass system at part load of the engine.
W …
Volume requirements for the intake systems of the Fiat 126p engine
The intake system, together with the valves and valve slots, fulfills complex and responsible tasks in the engine: supply and distribution to the engine cylinders of fresh cargo, and in the case of carburettor fueling - also preparation of the fuel-air mixture. In addition, the design of the intake system has an effect on …
Analysis of the design features of a delivery vehicle with a transversely located engine
Consequences of using front drive in a delivery vehicle and positioning the engine transversely, as is the case with modern passenger cars, they are numerous and mostly positive. They can be analyzed in turn by considering the following issues.
Number and quality of seats in the cabin.…
Construction of FIAT-Ducato cars, Peugeot-J5, Citroen-C25
Vehicle family, although individual models were sold under different names, is based on a single design solution. The family is divided into two groups of vehicles:
— type '1000' with payload 1070 kg and total weight 2450 kg,
— typ "1300" o …
Lateral positioning of the engine in a delivery vehicle
The "invasion" of the front drive with a transversely positioned engine, observed over the last several years, led to, that a passenger car with such a drive system is currently the dominant solution. The main advantage of this solution is the possibility of obtaining a large usable space in the vehicle. It enables …
