By
Posted in How To

If you’re considering buying a new vehicle, you have plenty of options. Factoring in the number of manufacturers, models, trim levels, and option packages, it can seem like there’s almost too many choices to make. Now, most people have an idea what they want. Perhaps a pickup truck, SUV, or a sedan. 

Choosing a powertrain can be one of the most challenging decisions buyers make. Today, vehicles often have multiple powertrain options for each model. Do you choose a traditional gas engine, a turbocharged version, or perhaps you have a diesel engine available. Of all the engines, the diesel powertrain might be the least understood.

So, we’ve created this comparison between gas and diesel engines to help you understand the differences. We’ll show you the pros and cons of each to help you make an informed decision. Read the rest of this entry >>

Although automotive tech has changed significantly over the years, four-stroke and two-stroke remain the two main combustion engine designs. Although the pre-owned cars at the NJ State Auto dealership in Jersey City feature four-stroke engines, many people can’t differentiate between two-stroke and four-stroke engines.

In this guide, our car experts discuss two-stroke and four-stroke engines and how they work. After reading this, you’ll have a better idea of how engines work. Read the rest of this entry >>

Understanding the Cam Shaft in Your Engine Part – III

Engine

The various configurations of the cam shaft will be discussed here. The 3 different camshafts are – single overhead cam, double overhead cam and the pushrod.

Single Overhead Cam (SOHC) – One cam per head indicates single overhead cam. Any inline 4 or 6 cylinder engines will have one cam. V-6 or V-8 engines will have 2 cams but one for each of the heads. The rocker arms of the cam presses down on the valves in order to open them. The valves come back to their positions with the help of extremely strong springs.

Double Overhead Cam (DOHC) – Two cams per head indicate double overhead cam. An inline engine will have 2 cams and V engines will have 4 cams but 2 on each head. Engines with 4 or more than 4 valves per cylinder have double overhead cams. A double cam shaft is capable of fitting enough lobes to work all the valves.

The crankshafts drive the cams in the double and single overhead cam engines with the help of a belt or a chain. These are known as the timing chain or the timing belt. If the chain or the belt breaks, the cam will not be able to spin anymore. The piston will hit the valves that are open. So these need to be changed or adjusted at regular intervals.

Understanding the Cam Shaft in Your Engine Part – II

Engine

In the earlier article we discussed about the general importance of the cam, the lobes and the cam shafts. We will now discuss about the basics of the cam shaft. The most important part of the cam shaft is the lobes. Their shape determines the performance of the engine. Variable cam shafts give better results. A fixed cam shaft is always bad for your engine.

When the piston moves downwards to allow for the intake of the air and fuel mixture, the intake valve opens. The intake stroke is called the top dead center or TDC. The intake valve closes when the piston reaches the bottom.

The exhaust valve opens just as the piston reaches the bottom. The combustion stroke is called the bottom dead center or BDC. The exhaust valve closes when the piston finishes the exhaust stroke. The valves are closing and opening at least 33 times a second when the engine is working at a high speed.

The piston is moving at a faster rate too. The air and fuel mixture, then, is also moving quickly and running into the engine cylinder. The longer the lobe remains open, the faster is the intake of the mixture. The faster the intake, the faster the cylinder accelerates. The end result is a faster and better performing engine.

Understanding the Cam Shaft in Your Engine

By
Posted in Uncategorized

Engine

The cam is a rotating piece in the engine of a vehicle that transforms linear motion into rotary motion and vice versa. The shaft around which the cam rotates is called the cam shaft. The operation of the cam shaft is extremely crucial in the performance of the engine.

The cams or lobes in the shaft push against the valves that allow the passage of air and fuel mixture in and out of the engine. The cam shafts rotate to open and close these valves in rhythm with the motion of the piston. The shape of the cam lobes influences the performance of the engine at different speed levels.

Different engine layouts have different cams. These affect the performance of the engine differently at different speeds. There are generally three different kinds of cams on engines – single overhead cam (SOHC) and double overhead cam (DOHC) and pushrods. A particular camshaft will be perfectly suitable at only a particular engine speed.

So, different cam profiles are needed for different engine speeds. The faster the engine moves, the faster the air and fuel mixture moves. So, preferably, the valves need to be open wider and for a longer period of time at higher speeds in order to improve the performance of the engine. The different shapes of the lobes help in this.

The Relationship Between RPM and Torque

By
Posted in Uncategorized

gearbox

RPM and Torque are some of the most commonly used terminology in the automotive industry, though few know what the meaning of the two terms actually are and how they translate to an actual driving experience. RPM stands for revolutions per minute. The basic understanding of this is the calculation of any object revolving in a circular motion around its orbit. On the other hand, Torque is a form of measure that determines the amount of load of a vehicle at any given point of time. The torque varies in different vehicles depending on the RPM.

The RPM is a type of determining factor for any form of power in the vehicle output. The torque of every vehicle is calculated based on the RPM at any given point of time. This basically means that the Torque of a vehicle’s engine depends on the RPM, however the RPM of the vehicle’s engine is determined on the power output of the engine. The torque is considered as a primary factor for determining load bearing vehicles. Since diesel engines are generally large carrier vehicles, it is considered to be the defining factor or selling point of the manufacturer.

RPM, as a general power determining factor is commonplace to both diesel and gasoline engines. At any given point in time, every power measure and reading will always be read at the rate of the RPM of the vehicle’s engine. To learn more about RPM and torque feel free to contact us.

What Does A Hissing Sound In The Engine Mean?

By
Posted in General Auto News

Is there a hissing sound originating from your used car’s engine? Well, if there is, there could be many reasons for that sound. A hissing sound from the engine generally isn’t a very good sign. However, there is no reason to panic.

In fact, it’s possible for most cars to carry parts that may create this hissing sound. So, before you jump to any conclusions, make sure you narrow down the problem to a specific cause. What you need to do is indulge in a thorough investigation to determine where that sound is coming from.

Look for visual cues. The more severe hisses are usually accompanied by some kind of release. For example, it could be coolant escaping from the radiator or radiator hose as a result of overheating. The coolant, in this situation, tries to escape in the form of steam.

If you can’t identify any visual cues, the next step is to listen closely, while the engine is still on. When you’re doing this make sure you follow a few safety measures. For example, don’t get too close to moving parts and if you have long or loose hair, tie it up.

Once you manage to identify the source of the hissing sound, start looking for symptoms. The symptoms will further help you decide what needs to be fixed.

Reasons for a hissing sound could include an overheating engine, in which case, you will need to fix the cooling system. It could also be that your catalytic converter or exhaust system is plugged. In this case, you will need to replace the parts in question.

If you’re concerned about the hissing sounds in your engine, please bring your pre-owned vehicle over to New Jersey State Auto Auction for a quick fix.

The Difference Between a Supercharger and a Turbocharger

By
Posted in General Auto News

A lot of you may want to look through used car places to find a fun car that can be tuned up and driven as weekend cars. A bit of sharp cornering, blazing straight lines and amped up torque and horsepower is best matched with a classic used car. As part of the performance upgrades, you may have come across turbos. There are two options- a turbocharger and a supercharger. Both systems do one thing, increase the power output of the engine without modifying the engine block itself. When done right, it can output up to 50% more power.

A turbocharger derives its energy from the exhaust. This exhaust flows through a turbine that in turn spins the compressor. The turbine can spin as fast as 150,000 RPM.

In case of the supercharger, it gets its power from the crankshaft, and forces air into the engine by compressing it. This boosts the horsepower as the increased air allows more fuel to be injected during combustion. These spin at around 50,000 RPM. Turbocharges get extremely hot and need to be well insulated, unlike superchargers which deliver high results at lower RPMs. Superchargers are also much easier to maintain than turbochargers which are more complex. Turbochargers though, are much quieter compared to superchargers, and are known to be more reliable.

Drive down to New Jersey State Auto Auction to pick out a used weekend car.
