Automotive Engineers Help Save Lives And Cash (genuine honda parts)
No commentsBy Mike Trudel
It turns out all those fancy automotive safety devices cannot only help save lives, they can also save cash. According to The Economic Impact of Motor Vehicle Crashes, roughly $230.6 billion was exhausted on motor vehicle crashes in 2000 in the U.S. Nearly 42 thousand people perished that year, and 28 million vehicles were damaged.
The same government report also revealed that 5.3 million individuals suffered non-fatal injuries, 39% of all traffic-related deaths were attributed to alcohol and such substance-induced accidents cost about $51 billion. Public tax revenues, amounting to $21 billion, paid the costs incurred by 9% of crashes. That’s $200 for each household in America.
But wait. There’s more. Lost market productivity was estimated at $61 billion, property damage at $59 billion, medical expenses at $32.6 billion and the cost of travel delays at $25.6 billion. Each fatality produced a discounted lifetime cost of approximately $977,000.
Active and passive safety systems developed by automotive engineers and their colleagues may be a bigger part of the answer than we might suspect. Systems currently being developed are addressing both the monetary and safety concerns of our roadways through devices that have automatic responses to dangerous conditions or events. For instance, adaptive cruise control adjusts the speed of the vehicle to maintain a preset time gap from the vehicle ahead. Active night vision uses infrared illuminators to help drivers to see better when driving at night and electronic stability control improves the safety of a vehicle’s handling, helping the driver maintain control of the vehicle.
Surprisingly, perhaps, these are just basic safety features - ranking amongst car navigation systems, keyless entry and hybrid cars as, yes, technological innovations, but old news to vehicle manufacturers. Lane departure and forward collision warning, pre-crash mitigation systems, side alert, pedestrian and road sign recognition systems are part of the new wave. These systems “read” the road using electronics, cameras and sensors. They alert drivers when they are drifting out of the intended lane, have another vehicle in their blind spots, are in danger of crashing or are distracted. These technological gems even respond to unavoidable crashes by enacting safety precautions, such as pretensioning motorized seat belts and applying brakes during the last 400 to 500 milliseconds before a crash, when there is little a driver can do to stop it.
According to the National Highway Traffic Safety Administration (NHTSA), 50% of all crashes involve “driver inattention.” It’s impossible to pinpoint how many crashes could have been avoided if there had only been some alert system warning drivers to pay more attention during critical moments. How many crashes could have been avoided by a single alert, some notification that another vehicle was in a driver’s blind spot? By shaving off four or five miles per hour before a crash by applying the brakes?
And while saving lives and preventing injuries is of the most concern, we cannot, in all reality, ignore the financial repercussions of roadway accidents. Billions upon billions of dollars are lost every year because of these crashes. Medical expenses, property damage and lost productivity are passed on to the average citizen in the form of higher taxes and insurance premiums. What if some percentage of this cost - even if slight - could be lessened by safety systems? One percent of hundreds of billions of dollars, after all, is nothing to scoff at.
Automotive engineers are critical contributors to advancing projects with aspirations of making roads safer. Without their expertise, none of the technology currently available would have been possible and neither would future innovations. What’s more, these talented individuals are integrating these devices so they are more affordable and, thus, more accessible to the masses.
In the near future, a modestly priced vehicle could have a myriad of safety features - forward collision and lane departure warning, road sign and pedestrian recognition, adaptive cruise control, pre-crash mitigation, electronic stability control, side alert. All of it. So kiss some automotive engineers today - hiding in their offices - and tell them you’re proud. They could just save your life … and at least a few bucks on your insurance policy.

LHD Cars Are They On The Wrong Side of The Road
By Daniel Millions
It might be a convenience that many would enjoy if the rules of the road were the same no matter what country you were visiting. This could also keep it from being so confusing to individuals when it comes to visiting other countries that use the left hand drive cars, especially if they are more comfortable in driving the right hand drive cars. The reality is however, that there are many countries who have opposite rules of the road.
Many years ago, archaeologists in England made a very interesting discovery. They happened upon a well-preserved path that had been continuously used for traveling by horses. By carefully studying the path, the archaeologists found that it was very clear that the riders that were riding these horses would normally tend to travel on the left side of the path. It was also found that these riders would tend to steer their horses by using their left hands.
The tradition of both the horses that were ridden, and the vehicles that were driven, driving to the left has remained the same throughout many centuries in England. During the 1700s a law was ultimately passed that would secure this driving preference. This law was called the Highway Act 1773, and it states that all traffic is to keep to the left when they are driving on the roads.
The United States also shared this preference of using left hand traffic, but then it was switched to using right hand traffic at about the same time period that England passed the law of the Highway Act 1773. The setup that was used for the horse-driven freight wagons is essentially what ended up prompting this change to take place into using right hand traffic. This preference of driving is still in effect to this day.
There are many places all around the world, as well as a majority of all the countries that prefer using the style of automobiles that are left hand drive cars, yet they prefer using right-hand traffic. There are some countries however that uses left hand traffic along with the use of left hand drive cars.
There are some countries that will allow its citizens to have the right in being able to choose which type of vehicle they would prefer to drive. They have the benefit in being able to decide if they would prefer to drive either a left hand drive car, or the right hand drive cars. The United Kingdom essentially uses the left hand drive cars, but there are some of its individuals that take advantage of being able to choose from a variety of European import vehicles that are right-hand drive vehicles.
Then, there are other countries that have banned the use altogether of its citizens being able to use any automobiles that have the wrong-side steering wheels. This could be perhaps due to the tremendous amount of confusion that it can create for the country’s normal flow of traffic.
Even with the variety of options and different rules of various countries, the left hand drive cars still remain the most popular and preferred choice for a majority of individuals all around the world today. A majority of the automobile manufacturers that are responsible for making both the left hand drive cars, as well as the right hand drive cars, still prefer making and producing the left hand drive automobiles.

The Performance of Antique Car Engines
By Peter Salmonford
It is often assumed that when an engine is new it gives its maximum power, but in actuality this is not the case. At the outset the bearings are tight and the bearing surfaces comparatively rough, and it is not until the engine has run some months that the highest power is developed. It is not to be assumed that up to this period the engine gradually increases in power, but that a higher power can be obtained from an engine after being well run in than when it is new.
In actual practice the engine gradually gives less and less power unless it receives the necessary small amount of attention to keep it up to its best pitch. The cause of this is a gradual loss of compression, chiefly owing to the burning away or pitting of the valves and their seats, the remedy for which is regrinding. Valve-grinding is a somewhat laborious process, but it is one which generally effects considerable improvement in the engine’s running, and it should be made a periodic practice, and not be left till the engine is running very badly, as the necessary grinding will then be somewhat difficult.
If a valve is examined it will be found that it has a flat angular surface on the underside of the head, and this surface rests upon a similar conical surface, called the valve seat, formed in the cylinder head. These two surfaces must be absolutely true and smooth so as to prevent any gas leakages when the valve is closed by the valve spring.
When the exhaust valve is opened the exhaust gas, which is an intensely hot flame, passes between these two conical surfaces, making them practically red hot, which is their normal condition during running of the engine. It is hardly surprising, therefore, that in course of time the surfaces deteriorate, and the necessity for regrinding can be ascertained from an inspection of the valve and its seat. If smooth and bright all round, the valve is in good order. If dirty and rough, it requires regrinding. When loss of power is experienced, to ascertain if it is due to loss of compression, the engine should be turned round slowly, with the switch off, and if the resistance on the compression stroke is not what it was when the engine was new, it is clear that there is a leakage somewhere, and the exhaust valve should then be examined as mentioned. Possibly only one or two of the valves are at fault, so the compression in each cylinder in turn should be tested in this way.
Before a valve is ground in it is, of course, necessary to remove it, and this, with its replacement, forms probably the most difficult part of valve grinding, on account of the stiffness of the valve spring, coupled with the fact that the parts are generally difficult of access, on account of the presence of the piping, etc.
