Fuel injection pump is an important part of automobile diesel engine. Fuel injection pump assembly usually consists of fuel injection pump, governor and other components installed together. The governor is the part that guarantees the low speed running of the diesel engine and the limit of the maximum speed, and ensures the relationship between the injection amount and the speed. As the most important part of diesel engine, the fuel injection pump is regarded as the heart of diesel engine. Injection pumps are so important, so where to wholesale to high quality injection pumps? The type and function of fuel injection pumpFuel injection pump can be divided into plunger type fuel injection pump, fuel injection pump - injector and rotor distribution type fuel injection pump three kinds. Among them, plunger injection pump is the oldest and most widely used, with high reliability; Fuel injection pump - fuel injector is the integration of the two, directly installed with the engine cylinder head, can eliminate the adverse impact of high pressure tubing (the engine is required to add a drive mechanism); Rotor-dispensing injection pump has only one pair of plunger, which mainly relies on the rotation of the rotor to realize the pressurization and distribution of fuel oil, with the characteristics of small size, light weight, easy to use and low cost.In our country, fuel injection pump plunger stroke, pump cylinder center distance and structure as the foundation, to match with different size of the plunger, several in one work cycle of oil and fuel injection pump, formation Ⅰ, Ⅱ, Ⅲ and several A, B, P, Z series, to meet the needs of all kinds of diesel engine.Function:1. Increase oil pressure (constant pressure) : increase oil injection pressure to 10MPa ~ 20MPa.2. Control injection time (timing) : the specified time for injection and stop injection.3. Control the amount of fuel injection (quantitative) : according to the working condition of the diesel engine, change the amount of fuel injection to adjust the speed and power of the diesel engine.  Top 9 high quality fuel injection pump suppliersAlibabaAlibaba states that the actual Alibaba.com website is a place for merchants to buy wholesale products from some of the best Chinese suppliers. These purchases can be shipped almost anywhere in the world. Not to mention, Alibaba boasts extremely low per-unit pricing because of its wholesale strategy located in the developing country of China. The members who sign up on Alibaba are almost strictly resellers, trading companies, and manufacturers. So, an online store could purchase wholesale products that are already manufactured, or they could customize items. AliExpressAliExpress.com, on the other hand, is a smaller subset of Alibaba, but it's still a large ecommerce marketplace for Chinese and Asian manufacturers and suppliers to sell goods. Many of the same suppliers are on both AliExpress and Alibaba.There's one large difference between the two: AliExpress has low prices at smaller quantities (you could buy one or two items for close to wholesale,) while Alibaba sellers typically require a minimum purchase order–similar to a standard wholesaler, except Alibaba's prices are typically lower and you can find millions of unique products through Alibaba. En.china.cn1.Types of suppliers: On En.China.cn, small commodities are being sold and you’ll find a complete list of different categories. Many of the suppliers come from China and most of them have a real factory.2. MOQ: MOQ varies among different suppliers. You can buy as little as one piece of some products. But most products’ MOQ is more than 10 pieces. Price varies according to the quantity purchased (e.g. buying 2pcs costs $5/pc, buying 200pcs costs $4.9/pc, buying more than 1000pcs costs $4.7/pc).3.Payment methodsUsually, you can pay through PayPal for small orders.

When installing the injection pump on the diesel engine, it is necessary to check the advance Angle of oil supply and adjustment. After 500 hours of diesel engine operation, the fuel supply advance Angle should be re-checked and adjusted.1. National standard light diesel oil must be adopted. The diesel oil should go through the precipitation filtration for 48 ~ 96 hours.2. At ordinary times, it is necessary to clean the diesel oil tank and the diesel oil filter.3. Check the oil in the governor every day, and add enough oil in time when insufficient.4. If there is skeleton oil seal between the fuel injection pump and governor, oil should be filled separately.5. If the oil level is increased due to oil dilution, it indicates that the fuel injection pump and the oil transfer pump are leaking seriously and should be eliminated in time.6. After 100 hours of operation of the diesel engine, change the oil and clean the filter screen of the oil pump.7. The fuel injection pump shall not be disassembled and adjusted at will, especially for the part with sealing mark. When it is really necessary to disassemble and maintain, it shall be carried out after cleaning the place. ConclusionAll the websites that are mentioned above are reputed wholesale websites. The best part of opting for the wholesale website is they are going to offer you with affordable prices and great variety.   

This is an article about the injector for you, and tell you the brand name of the injector and the reputable supplier. This article is divided into the following sections:1. What is fuel injection?2. Brand introduction of fuel injection3.9 high quality fitech fuel injection suppliersFirst, let's start with the first part. What is fuel injection?About fuel injectionThe fuel injector is a precision device with very high processing precision, which requires a large dynamic flow range, strong anti-blocking and anti-pollution ability and good atomization performance.The spray characteristics of the fuel injector include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle. These characteristics should meet the requirements of the diesel combustion system to complete the formation and combustion of the mixture, and to achieve higher power and thermal efficiency. It has the following effects:1. Increase oil pressure (constant pressure): Increase the injection pressure to 10 MPa to 20 MPa.2. Control injection time (timing): Inject oil and stop injection at the specified time.3. Control the fuel injection amount (quantitative): According to the working condition of the diesel engine, change the amount of fuel injection to adjust the speed and power of the diesel engine.In addition, fuel injection can be divided into the following categories:(1) Shaft needle type electromagnetic fuel injectionWhen the fuel is injected, the armature drives the needle valve to rise from its seat surface by about 0.1 mm, and the fuel is ejected from the precision gap. In order to fully atomize the fuel, a needle of the injection shaft is ground at the front end of the needle valve. The injector suction and fall time is about 1~1.5ms.  (2) Ball valve type electromagnetic fuel injectionThe valve needle of the ball valve is light in weight and has a large spring preload force for a wider dynamic flow range. The ball valve has an automatic centering function and good sealing. At the same time, the ball valve simplifies the structure of the metering part and helps to improve the accuracy of the fuel injection.   (3) Chip valve type electromagnetic fuel injectionrThe light-weight valve and bore seats are combined with a magnetically optimized injector assembly that allows the injector to have a wide dynamic flow range and high resistance to clogging.     (4) Injector with lower fuel injectionBy adopting the bottom oil supply mode, since the fuel can continuously flow out from the upper portion of the injector through the inner cavity of the injector, the cooling effect on the metering portion of the injector is very obvious, so that the generation of the air resistance can be effectively prevented, and the hot start of the automobile can be improved. Reliability.   Knowing these information about fuel injectors, do you want to know some cost-effective brand-name injectors? I don't know if you have heard of Fitech, a cost-effective brand.
