After Peugeot introduced its new Peugeot 308 at the Frankfurt Motor Show in September, it will become the first European automaker to offer all-LED headlights as standard in most of the trim levels for this compact range. This is quite a big progress in technology, since only a few years ago, LEDs were the prerogative of only high-end cars, such as the Audi R8 and Mercedes-Benz CLS. LED headlights are almost three times more expensive than comparable xenon ones.
Peugeot is not the only low-cost automaker seeking to increase its competitiveness through technology. Volkswagen’s Spanish division, Seat, offers Best LED Headlights On The Market as an option for high-end versions of the Leon Compact in Europe, while Ford plans to offer the next-generation Mondeo to all-LED headlights from Valeo. Serial production of the new Mondeo is scheduled for next year.
In the meantime, low-cost automakers are just beginning to add all-LED headlights to their models, premium brands such as Audi are rapidly expanding the use of this technology to all of their model lines that are included in lower segments.
Audi is an early leader
Audi, who was an early leader in differentiating its models through lighting systems, offers LED headlights on the A3 as an option. Andrew Herzig, an industry analyst at IHS Automotive, predicts that LED headlights will become an option for all future Audi as they become available or updated.
Many factors determine future trends. In particular, the designers liked the LEDs. Compact, square cells with a side of 1 mm, allow them to create a clear picture of the headlights and rear lights.
Engineers like LEDs for another reason, since they require much less energy, generate a directional beam of monochrome light and do not heat up. However, these three letters LED (as LEDs are called in English), cause a toothache for financiers. But that too will change soon.
In the crisis European market, automakers are struggling to look for ways to develop or at least maintain sales. And one option is to offer more cars with an extended list of equipment for the same price. LEDs can be another attractive weight in this fight. Anyway, this is what Ford, Seat and Peugeot are confirming now with their actions.
Halogens remain the cheapest source of bright light for long distances. However, they are too inefficient, as they convert only 5 percent of the energy consumed into visible light. Xenon is still at the growth stage, increasing its share as this technology develops.
Compared to halogens and xenon, LEDs are still too expensive. As Herzen wrote in his time: “They are too far from the people.” However, here too, the development of technology leads to a reduction in cost. So, today, the cost of low-end LED headlamps is comparable to high-end, fully adaptive xenon headlights.
Tips on How to choose a pneumatic grease gun.
Tips and flexible hoses.
Despite the fact that the grease nipples come in different versions, with a tilt angle between the threaded and filling ends of 45, 90 and 180 degrees, there are situations when you have to choose a position for injection. For example, when lubricating the cardan shafts, the car must be moved to install the tip of the lubricant syringe.
A straight or bent steel tube, like the Vorel 78050, is less convenient for use in hard-to-reach places than a flexible polyamide hose with polyurethane reinforcement, like the Groz 42921. with one or two springs at the ends, its tip is harder to fit coaxially into the grease nipple.
Without supporting and sticking with the second hand, the hose of the automobile syringe bends, the tip deviates from the axis, its fit to the spherical surface of the grease nipple becomes leaky and the lubricant does not move along the channel, but comes out.
Nozzles syringes differ in thickness of the petals, the higher the pressure generated, the thicker and in their number. Four-collet sleeves, compared to three-lobe, allow you to put the tip on the sphere at a large angle of deviation from the axis of parallelism.
Penetrating into narrow gaps and places with limited access is convenient when the outer diameter of the nozzle is minimal. However, for grease syringes that develop a pressure of 690 bar, like the Groz 42701, it is always greater than that of the Groz 43251 with 240 bar.
Tubes for filling with lubricant.
When choosing a tool, specialists with experience with automotive plunger syringes pay attention to a number of design features.
Bending the lever handle should be done in such a way as to avoid the danger of damaging the fingers of your hand while holding the tube in any place, like in Yato YT-07041. The tank body can be steel, like the Vorel 78040, aluminum, like the Intertool HT-0063 or transparent plastic, like the Vorel 78031. The thread on the outer part of the tube is cut or rolled, for screwing the front cover. squeezed from the inside. The last performance is preferable, because threads on such grease guns are less sensitive to mechanical damage.
Metal tubes, despite the great structural strength, wall thickness from 0.75 to 1.5 mm, with a drop covered with dents and the material begins to squeeze past the piston.
Transparent housings made of rigid polycarbonate are more convenient for visual identification: the type of lubricant remaining in the tube, the presence of air bubbles or foreign matter in it. The scale applied to the oil filler syringe allows you to determine the amount of pumped out or filled in the gearbox or gearbox oil.
