Engine Manufacturing

The Engine's History

1876 four-cycle engine

The first successful four-stroke internal combustion engine was built in 1876 by Nicolaus Otto.  His invention, 被称为“奥托循环发动机”，提供了第一个作为动力的蒸汽机的实用替代品 source.

Combustion is the chemical process of releasing energy from a fuel and air mixture.  The expanding combustion gases push the piston, which rotates the crankshaft.  Then, through a system of gears in the powertrain, motion drives a vehicle’s wheels.

Throughout the 20th century, the two most common internal combustion engines manufactured were the diesel and petrol engines.  今天，在21世纪，电动发动机开始成为主流 newer technology being introduced every day.  This is an important point to mention, as newbb电子 needing worn by employees must change within different manufacturing plants.  Example being, workers that manufacturer electric 发动机正在使用更薄的金属，因此需要更高级别的防割伤手套.

Engine Products

发动机有许多不同的形状和大小，并且是为许多不同的目的而制造的.  Here is a quick rundown of the different types of engines.

Gasoline Engines

在这种内燃机中，燃料与空气混合，然后被引入发动机 cylinder during intake.  With fuel-air inside the engine, a spark ignites, causing combustion.  Hot gases produced are used to drive the pistons.

This type of engine is the primary engine used in automobiles. Other applications for this engine include aircraft, motorcycles, motorboats, and small engines.

Diesel Engines

在这种内燃机中，只有空气被引入发动机，然后 compressed.  The diesel engine then sprays fuel into the hot compressed air, causing it to ignite.

然而，重型柴油发动机主要是为货运卡车制造的 also be found in light- and medium-duty trucks.  They are used for several purposes: heavy-duty transportation, medium-duty trucks, and for industrial machinery engines.

In 2017, there were roughly 900,000 diesel engines manufactured in the U.S.

Electric Engines

Electric engines are powered by an electric current that generates a magnetic charge and turns the driveshaft.  These engines utilize large lithium-ion batteries or batteries made with newer technologies.

An Electric Vehicle's Battery

电动发动机有两种基本类型:全电动汽车(aev)和插电式混合动力汽车 electric vehicles (PHEVs).

Economic Impact

Ultimately, the global automotive engine & parts manufacturing industry is linked to motor vehicle production, as engines are the essential component of the automobile.  The industry is forecasted to hit $299 billion in 2019.

Automotive engine & parts manufacturing involves making the following products: camshafts, crankshafts, engines, fuel injectors, pistons, valves, and pumps.  With regard to this industry resource page, we highlight the manufacturing of engines, not all the components that make up this industry.

发动机和涡轮工业与更多的工业生产相关联，预计将达到 $55billion in 2019.

Companies

Honda is the world’s largest engine manufacturer, producing more than 23 million units annually.  Have you ever wondered who makes the best automotive engine?   Well, Ranker knows the answer to that question, as over 81,000 people have voted on the topic.  Honda is ranked the #1 engine by voters.

Many automotive companies manufacture engines in their own automotive plants.  However, some treat the engine as they do other parts and source from outside suppliers.  GM has sourced from others over 这些年来，包括铃木的3缸组合，但他们的发动机更多地是在国内生产的 recent years.

Engine manufacturing goes beyond just the engines found in automotive vehicles.  The Truck and Engine Manufacturers Association represents manufacturers of internal combustion engines.  Their collection of members represents some of the largest industrial companies operating across the world.

卡特彼勒、康明斯和通用电气公司是这份名单上最大的三家公司.  Here are some of the many areas where you will find industrial engines used:

• Buses
• Electric generators
• Farm, construction, and industrial equipment
• Lawn and garden
• Locomotives
• Marine vessels
• Motorcycles
• Power transmission equipment
• Turbines Trucks

As we mentioned above, engines serve a wide range of purposes.

Die-Casting the Engine Block

The companies mentioned above manufacture a multitude of parts, with the engine block making up the core component.   它是容纳数百个部件的主要结构，使发动机能够正常工作.

Engine Block

The manufacturing of the engine block is primarily accomplished by sand casting.  The reason for this is that the 发动机必须能够承受燃烧时产生的极端压力.  Green sand molding casting is the process most widely used.  This means it must withstand high temperatures and constant vibrations.

Stages in Manufacturing the Engine Block

发动机缸体是一件式部件，是汽车中最大的一块金属.  It is where combustion converts into mechanical energy.

Here are the steps for manufacturing it:

你可以想象，在热和金属周围工作意味着newbb电子平台安全手套，由 DuPont Kevlar®, are an ideal choice for workers.  Be sure to check out newbb电子平台 Safety’s industry page on foundries for further casting information.

Assembly and Testing

Once the engine block is manufactured, a working engine is only halfway complete.  An engine consists of an assortment of mechanical and electronic components, all of which must be assembled into a working whole.

A robot is at the heart of most of this process, completing tasks like installing the pistons into the cylinder bores and attaching pistons to the crankshaft.  However, the engine assembler still closes up the back of the engine block, tightens bolts, arranges wires, and moves the engine to the motor vehicle assembly line.

Engine Being Assembled

Employment

There are around 96,000 employees manufacturing industrial engines.  Whether it’s an automotive engine or an industrial diesel engine being manufactured, many workers find occupations that provide employment.   Here is a look at the occupations found in this industry.

Occupations

Manufacturing engines, like most other automotive industries, requires assemblers that fasten piping, install wiring, and cut out parts.  Many of the same occupations that make up the part manufacturing industry also work in this industry.  However, we’re going to highlight the engine assembler.

As you might already have guessed, where the automobiles are manufactured is where you will find most U.S. engines being manufactured.  Here are the states employing the most engine assemblers.

Automotive parts manufacturing is where you find most engine assemblers.

Safety

What do 91% of engine assemblers say their work requires every day?  If you guessed newbb电子, you would be correct.   与其他汽车行业相比，制造发动机并不像其他行业那样危险 metal stamping; however, it still has more injuries than the overall industry average.

Manufacturing engines is about 16% more dangerous on average.  It might be even higher if not for the fact that most of the engine manufacturing is an automated process.  With that said, employees still come into contact with heat, abrasive sand, oil, sharp metal, and numerous other hazards.
