Is the engine in your car or late model truck worth rebuilding? Is the time , trouble and expense worth it or should you check one of other alternatives available to you such as a used engine , a full or partial professional rebuild or a factory service like rebuild – many of which now are being done offshore and being shipped back to U.S. automotive consumers ?

The do it yourselfer is faced with these options to evaluate when it comes to the dreaded time of a potential engine overall. Most likely you have gotten a good number of relatively trouble free services from your automotive engine and are now faced with the prospect of an engine overhaul. The decision to replace the engine bloc, piston, connecting rod assemblies as well as crankshaft depends on a number of factors, with the number one consideration being the condition of the engine block. Other considerations are cost, ready access to machine and auto shop facilities, parts availability, time required to complete the project and finally the extent of prior mechanical experience on the part of the do-it-yourselfer home auto mechanic.

Next consider the value of the vehicle. It has turned out that frequently the total end cost of the parts required to complete the task of rebuilding the engine is greater and more than the actual value of the vehicle. It can be said that often ego and pride of ownership gets in the way of a fair and true evaluation of the situation, its costs and reasonable conclusions on the suitability of the project at all. As a case in point one proud owner of what might be considered a truck that was long past its prime and in great need of repair convinced himself that expensive repairs were in order by himself when a quick tour of local area junkyards should of convinced that the truck itself could be replaced by any of the similar vehicles that were laying about these auto parts recycling facilities.

In such situations where the cost for a full engine overhaul is greater than the cost of a full and proper engine rebuild one option to consider is a used engine from one of above auto junk yards. True the engine may not have the full engine life of a rebuilt engine but there may be more than enough lifespan in one of these replacements which come at a much lower cost and may indeed outlive the body components and lifespan of the vehicle itself. In addition most of the professional auto parts recycling shops will both have tested and warranty the engine for a reasonable initial automobile test and evaluation time period.

It can be said that the vehicle may seem to have great value to you. The question to ask is “If I sink in this money and time of a full rebuilt engine will anyone pay me more for my vehicle or if I sell this vehicle will I get my money back?” The answer is usually “Probably not”. However it can be said that devil you know is better than the devil you do not. You will have a vehicle whose history and maintenance background is well known to you. You will know the quirks and characteristics of the vehicle – of what to expect and what repairs as well are upcoming. Thus said sinking money and time into rebuilding your engine or engine block may make good sense to you overall in the end.

Recent innovations in automotive engineering have produced active safety systems ranging from side alert, often called blind spot warning, to adaptive cruise control, to collision detection and warning. What this means to the average consumer will change over time as these products become increasingly available. What this means to the automotive engineer is increased attention to safe technology.

Many impressive innovations beyond the now customary car navigation system have existed – and even been on the market – for years now. Adaptive cruise control has been available since the early 19990s. Electronic stability control has been an option for many vehicles since 1995. Scanning radars, crash sensors, pre-crash mitigation and vehicle and occupant safety systems are also emerging. Such systems offer insights into how roads can be made safer in generations to come and where automotive technology is heading. In other words, as cars become “carputers,” automotive engineers are driving shifting technologies.

The myriad of promising innovations includes vehicle occupant safety systems. For example, a crash sensor generates a signal based upon a potential crash or one already transpired via a continuously variable severity output signal. If an accident has occurred, sensors signal certain actions like deployment of airbags. If an accident is likely to occur, sensors can alert the driver in various ways so that she or he can try to take necessary actions to avoid an accident and/or the sensors can take action themselves by pretensioning seatbelts or initiating automatic braking. In many ways, this process is not dissimilar to the functioning of the human brain: The brain sends a signal to the body to complete an action, often in response to stimuli received from the outside world. Who knew humanity would serve as its own model for creating devices designed for our safety?

Often, though, such examples of automotive technology are integrated into high-end, expensive cars first, due to high pricing. As the benefits of these products become more widely known and their popularity expands, costs decrease due to economies of scale and advancing technology. As research and development pay off, these advanced products become more widely distributed.

The advantages of automotive system and component integration expertise will continue to increase over time. Such knowledge may be paramount to an industry focused on better fuel economy, safety advancements and financially feasible products. Engineers versed in not only the basics of these systems but also in how to integrate them is only the beginning. Savvy engineers who are engaging in up-integration – adding software that makes one electronic module do many things – and sensor fusion – using complementary technologies to enhance object detection and classification – may have an edge in an ever-competitive job market.

In the rush to meet consumer demand and stay competitive, suppliers tend to be increasingly eager to develop ways to integrate safety and other technology systems. Many vehicles currently come with automatic on/off, high/low beam and rain sensor technology for instance. A separate camera, of course, is not necessary for this. Install a camera for a lane departure warning system, and suddenly a world of possibilities opens up. Intelligent headlight plus pedestrian and sign recognition programs can also be added, to name a few, without the need for additional cameras. Separate module manufacturing for each technological innovation becomes unnecessary. Multiple functions and features on the same apparatus decrease cost and increase functionality

So, what’s next? It seems to be the perpetual question that automotive engineers ask – no matter how far we advance. Perhaps an entirely self-driving car. Perhaps hover vehicles on highways, following designated pathways and communicating with surrounding vehicles to avoid crashes.

What do consumers want? The evolution of technology. Inventions born of new ideas. And, ultimately, innovative products that can even make us all safer. It’s the engineers, though – the technological innovators themselves – who make it possible.
