The spray-guided injection is the only one located close to the spark plug because the fuel sprays in at the end of the piston\u2019s compression and ignites immediately, resulting in a good burn.<\/p>\n\n\n\n<p><a><\/a>By comparison, the suction created from the piston moving down draws in fuel in the air-guided system. Compared to the wall-guided system, the gas enters a swirl cavity on the piston as it drives toward the spark plug where the fuel ignites.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"GDI_Engine_vs_Fuel_Injection\"><\/span><a><\/a>GDI Engine vs. Fuel Injection<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>GDI systems differ from standard fuel injection as the nozzle directly injects fuel into the combustion chamber. However, older fuel injection systems inject gas into the manifold, not the combustion chamber.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_long_will_a_GDI_engine_last\"><\/span><a><\/a>How long will a GDI engine last?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>While GDI engines burn fuel more efficiently, lower emissions, save money, and are better for the environment, they lose points when looking at engine maintenance.<\/p>\n\n\n\n<p><a><\/a>Simply put, this system will either work inefficiently or not at all if not properly maintained. Maintenance issues arise due to how the engine functions, a lot of carbon accumulation is very likely to form and needs to be properly cleaned from time to time.<\/p>\n\n\n\n<p><a><\/a>Furthermore, some people unknowingly use poor quality fuel, causing solids to get left behind, which may mean that the engine needs maintenance sooner than expected. Before buying a car like this, a buyer should learn about maintenance considerations to keep the engine running in peak form.<\/p>\n\n\n\n<p><a><\/a>Consequently, the answer to the question \u201chow long will a GDI engine last?\u201d has to come down to how well the owner maintains it. If well maintained, the engine will be reliable and should last a long time, and maintain good performance over the 100,000-mile mark with very few issues.&nbsp;<\/p>\n\n\n\n<p><a><\/a>On the other hand, if a person does not practice good maintenance, the engine will likely work poorly and may not last very long.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Cars_Have_GDI_Engines\"><\/span><a><\/a>What Cars Have GDI Engines?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>The list of cars that use GDI engines is <a href=\"http:\/\/www.crcforshops.com\/assets\/crc-gdi-vehicles-mar-2017-list.pdf\" target=\"_blank\" rel=\"noopener\">too vast<\/a> to list here as it encompasses approximately 50% of the entire car industry.&nbsp;<\/p>\n\n\n\n<p><a><\/a>Some popular brands include:&nbsp;<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Ford Focus, Fiesta, and Mustang<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Honda Accord and CR-V<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Hyundai Accent and Elantra GT<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; And many more<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Benefits_of_Cars_with_GDI_Engine\"><\/span><a><\/a>Benefits of Cars with GDI Engine<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Reduced fuel consumption<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Saves on gas<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Idling in city traffic can save as much as 20-25%<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Lower emissions<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Eco-friendly<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; 10-15% more power<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Cleaner burning<\/p>\n\n\n\n<p><a><\/a>\u25cf&nbsp;&nbsp;&nbsp;&nbsp; Less soot buildup<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_Problems_with_GDI_Engines\"><\/span><a><\/a>Common Problems with GDI Engines<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>One of the biggest problems common in GDI engines is an unknowing owner using low-quality fuel.

This necessity is due to the precision operations, so the system needs cleanliness to function as designed.<\/p>\n\n\n\n<p><a><\/a>Specifically, the valves and pistons need to stay clean so that the engine does not lose power, waste fuel, and burn oil. Choosing the right kind of oil for the engine is a big part of getting this right too, and each manufacturer\u2019s manual will state which oil is best for that engine.&nbsp;<\/p>\n\n\n\n<p><a><\/a>No matter how good your oil is and how high-quality your fuel is, carbon will build up inside the engine. As stated earlier, this is most notably a problem around the valves and pistons.&nbsp;<\/p>\n\n\n\n<p><a><\/a>If maintained properly, removing light to moderate carbon buildup should not be a cause for concern. The easiest way is to purchase an aerosol intake system cleaner. There are several brands on the market, Berryman, Seafoam, and CRC, to name a few.<\/p>\n\n\n\n<p><a><\/a>There are many benefits to keeping the engine clean by performing this relatively simple maintenance step. First, if done early in the life of a vehicle, there is a good chance that a critical amount of carbon will never accumulate, eliminating the need for an expensive professional cleaning.<\/p>\n\n\n\n<p><a><\/a>We recommend working in regular cleaning as routine maintenance, just like changing the oil every few months. Do them around the same time, and there is no reason you should not have a clean, long-lasting engine.<\/p>\n\n\n\n<p><a><\/a>Finally, we advise performing an oil change after using the intake cleaner. To get the best clean, drive the vehicle for about twenty miles to give the intake cleaner time to do its job. Then the oil change will remove everything and leave a clean engine behind.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_often_should_you_clean_a_GDI_engine\"><\/span><a><\/a>How often should you clean a GDI engine?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>Unfortunately, this is not a one answer fits all situations question. People who live in cities who experience start and stop driving and more pollution in the air will accumulate more carbon buildup in the engine. However, people in rural areas with cleaner air and better driving conditions experience fewer problems.<\/p>\n\n\n\n<p><a><\/a>The next part is which method the owner wants to employ. If a person does not mind performing maintenance on their automobile, the aerosol cleaner method described above should work well.<\/p>\n\n\n\n<p><a><\/a>However, some people, for various reasons, can\u2019t or won\u2019t perform this maintenance. For these people, letting it build up and eventually getting a professional cleaning is probably the answer.<\/p>\n\n\n\n<p><a><\/a>In this case, most people wait until the 50-100k mile mark to let a professional do the cleaning.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"GDI_engine_cleaning_cost\"><\/span><a><\/a>GDI engine cleaning cost<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>The cost of this cleaning will largely depend on which method a person chooses, home maintenance or professional cleaning.<\/p>\n\n\n\n<p><a><\/a>With home maintenance the aerosol cleaner costs about $12-$25, depending on the brand.<\/p>\n\n\n\n<p>Professional cleaning costs a lot more but comes around much less often. <a href=\"https:\/\/www.yelp.com\/costs\/auto_engine_cleaning\" target=\"_blank\" rel=\"noreferrer noopener\">Estimation<\/a> places the cost around $165 on average.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Switch_to_a_GDI\"><\/span><a><\/a>Why Switch to a GDI?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a><\/a>In terms of savings on crucial factors like fuel costs and efficiency, the answer is simple: A GDI engine saves money both driving on open roads and when stuck in a traffic jam in a city.<\/p>\n\n\n\n<p><a><\/a>This type of engine is eco-friendly due to lowered emissions, and everybody wants to breathe cleaner air. It only comes at the cost of needing some required maintenance, which is well worth it to save at the pump and help the environment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>GDI engine stands for Gasoline Direct Injection engine, which is the most modern form of fuel injection and has come standard on many automobiles for&#8230;<\/p>\n","protected":false},"author":2,"featured_media":603,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[],"class_list":["post-602","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-engine","wpcat-8-id"],"_links":{"self":[{"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/posts\/602"}],"collection":[{"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/comments?post=602"}],"version-history":[{"count":2,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/posts\/602\/revisions"}],"predecessor-version":[{"id":621,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/posts\/602\/revisions\/621"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/media\/603"}],"wp:attachment":[{"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/media?parent=602"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/categories?post=602"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycarmakesnoise.com\/wp-json\/wp\/v2\/tags?post=602"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
